Additionally, you don't have to limit yourself to the Nigerian market alone. I don't see other game developers limiting themselves to just one country alone.

Are there mods in this section?

zicjoe: console.log?? Explain pls.

It is a common object/method provided by debuggers that allows you to log information to the Javascript console that comes with most browsers. The shortcut for the Javascript console on most browsers is f12. It's a great way to try out what your code does and not as annoying as the alert function.

Clear?

[size=32pt]Simple Javascript Challenges for Beginners[/size]

Hey guys, here are some simple javascript challenges to try out.

[size=24pt]1. Looping a triangle[/size]

Using a for loop, write a program that makes seven calls to console.log to output the following triangle:

#
##
###
####
#####
######
#######

[size=24pt]2. FizzBuzz[/size]
Using a for loop, write a program that uses console.log to print all the numbers from 1 to 100, with two exceptions. For numbers divisible by 3, print "Fizz" instead of the number, and for numbers divisible by 5 (and not 3), print "Buzz" instead.

When you have that working, modify your program to print "FizzBuzz" for numbers that are divisible by both 3 and 5.

asalimpo: d light situation is bloody.
Evry month for the past 4 months has been bleak. Cud u giv me an idea of how much it cost to run a gen in a wk/month usg ur cafe situation? Wud b appreciated.

On the average, we spend 1000 naira on fuel per day. There are days we spend more than that though.

Chrylich: and another point to add,
since this competition is aimed at beginners, i see no reason why additional points should be added for quick submission.. beginners are meant to struggle and this is a "code from scratch" competition, submitting a project just after few days doesn't potray one to be a beginner..
and don't forget we are in Nigeria, the situation (electricity) is different everywhere..
IMO

Nice point there but you should also note that we are not just doing this for now but for the future. When you start doing jobs for clients, and you are given a deadline, you will be able to meet up on time because it is not something that is new to you also you will be able to handle yourself better when under pressure. Besides submitting on time is just 10% of your total score.

I do agree with you about the issue of electricity but instead of complaining, this should make you more productive. You only have light for one hour in a day? then use it well cos at least you know you have achieved something in such a limited time. Additionally, you can make friends with those people you know are always "lightful (you know, those kind people wey dey always dey get light no matter what)".

All our ogas at the top dem all started from somewhere and I'm sure as hell, they also had this kind of wahala disturbing them but they all kept plugging away.

But this light issue tire me sef, where do you stay? I work in a cafe and na gen we dey use all through except sometimes wey nepa get pity for the less privileged na im dem dey bring light but electricity (more like generatortricity) is fairly stable.

If God bless me, whether I go start my own hub for developers sef. Dey pray for me sha.

donpeey22: I never said that's the only criteria. The lady must be rational and know how to do good deeds without being induced by the threat of a non-existing hellfire.

I guess by ''God fearing'' you are actually referring to Christian women. Juju priestesses are ''God fearing'' too but they don't do their deeds for fear of hell fire.

Your only criteria is that the lady be atheist?

All dis people wey dey carry atheism for head sef.

Or you could just make money and all you would have to say would be ''babe show face''

ClintonNzedimma: thanx bro but i think i need ebooks for beginners

Apart from the first one, the rest are suitable for beginners. You can also check out these sites to grasp some of the basic concepts. They are all beginner friendly:

Karleb: Questions:

1. Do you mean I can only do that with a computer, cos I don't have one but I have an android phone.


2. Do you mean Dropbox can also perform this function.


3. I'm sorry for derailing your thread.

1. Yes, I don't think an android phone is suitable for that.

2. Yeah but I prefer drive and besides you have to be on premium package to host with dropbox

3. You're not really derailing. We are here to help each other on any subject. Javascript just happens to be the main focus

An app that can cure ebola?? cure

Karleb: You gorrit

I wanna learn the a_z, sir.

Well, there is nothing much to learn. Google drive is like Dropbox, a cloud based service that allows you to store documents, photos, videos etc online. It offers you 15gb of storage.

Umm, what else, you can use it to host your simple web apps and or web site, all you have to do is to upload the codes/files/images etc that make up the site into a folder and make sure the arrangement is the same as it is on your local computer (you could just upload the entire folder at once with all the files inside).

Click on your html document, it will open up a preview of the code that makes up the html document, at the top, you should see a link called "Open", click on it and it will open up a new page still containing just the code but this time at the top, you should see a link called "preview" and when you click on it, it will open up the web page as it should be displayed in a browser.

One thing to note: make sure you share the folder as "public on the web" so that it can be accessed by all.

When it opens up the web page, it will generate a funny looking url for your site, just copy it and share. (you can shorten the link using a url shortener though)

Daz all.

Karleb: But I could swear you've been hosting your codes before you met bitbucket, as in the competition.


BTW, I meant Alhaji.

Do you mean google drive?

Karleb: Pastor blueyedgeek, please can you gimme the link to tthe website you use to host your codes.


I already have bitbucket.

Pastor bawo? I use bitbucket too. I'm still trying to wrap my head around this whole git stuff so I'm not big on that.

[quote author=]Aside of the foolishness of some people on this thread, this is an otherwise good thread.[/quote]Yeah. Good morning and welcome.

Djtm: your browser should have stopped the script. What browser are you using?

I have most browsers installed but I was using Google canary at that moment in time.

How far have we come with Javascript?

Yesterday I crashed my browser while using the while loop (pun intended). I forgot to add the decrement operator inside the code block and it took me a while (again, pun intended) to figure it out.

Good morning peeps.

Invitation Sent!!

khadaffi: The problem I see here is that while this thread was created for beginners we have some advanced learners who assume themselves to still be beginners or learners. Otherwise how do you expect someone who started learning Javascript just about a month or two months back to join you in creating an app or whatever.

My humble submission: create another thread and state the level of experienced programmers who will work on any idea you come up with. Even me myself , I started this Js about 3months ago, and I doubt if I can answer up to five of those questions posted there without visiting google

Please you guys should leave here if you feel your level of experience is above what is done here. Simple

Aptly put.

Dlastofmykind: You dis guy again....... u still wanna collect another 6k.
Chai, Daniel...... There is God o!

The money is not my main interest. Besides, this time around, it's going to be tougher and way more interesting. I hope more people sign up for the challenge to increase the difficulty to '' *hard mode* ''

Like say u sef no register.

Thumbs up man. I don't have much technical jargon to say jare, it's pretty cool, I especially like the way the page fades out on logout and fades in to reveal the login page.

sisqology: Erm... My system crashed! Lost all I had.

For real? And I was here thinking you had lost interest with continuing the challenge and I'm sorry for that. I'm also sorry your system crashed, how did it happen?

davidsmith8900: Another challenge/study group going nowhere. Lets make JS apps that will make us money instead of making inept n rigged challenges and study groups on this forum. That will definitely help out the poor that is really in need than those who have money and want to hide info and money to themselves.

1. An app that will teach people JS.
2. An app that display your code in real-time devices
3. An app that will convert HTML/JS into other languages like Java & C++.

1. how can you teach people Javascript if you do not understand it?
2. what is that even supposed to achieve?
3. again, to what end?

Now, let's get started. Learning JavaScript: Resources to get started

If you are just getting started with JavaScript, you might get confused on where to start and how to start but before getting started, here are a few things to take note of.

* Try to understand what you are learning. Javascript is used to script the behaviour of web pages and it is no way related to the Java programming language, original name was Livescript but was changed to be similar to the then hot Java programming language additionally, it is a full fledged programming language.

* You may have heard about the popular JavaScript library, jQuery but note that jQuery is not a replacement for JavaScript. In fact jQuery just contains a bunch of pre written JavaScript functions to make your coding life easier but you still need to understand Javascript in order to use it properly. In fact, if you become a JavaScript ninja, you could decide to build your own library just for kicks

* Now, to really get started, there are many easy way to get started learning JavaScript and to be honest, things have become much easier for us in this generation. There are many online schools springing up left right and center just waiting to tutor you on the latest technologies so that you can become a coding ninja. If you haven't had a taste of JavaScript before then you can familiarize yourself by reading through our very own Dhtml's tutorial on the subject (although it has been discontinued but not to worry).

-- here are a few online schools to learn Javascript for free

++ Codecademy: their tagline says it all, "learn to code interactively for free". Just sign up and get coding. Trust me, you'll love it but don't over depend on codecademy for all your needs because it somehow gives you a false sense of accomplishment when you are being spoon fed through out but it's still a good place to start.

++ Learnstreet: Learnstreet is another good place to get started, theirs is a bit similar to codecademy, you write code right there in your browser in the online console and it also comes packed with many different exercises and video tutorials.

* Get a good book and start reading. Unfortunately, I don't have any favorite as recommendations as I just read reviews and download the e-book version but if you still don't know which good book to start with then I will recommend a few:

-- Javascript: the definitive guide: okay, I admit, I only opened this book once and then run away because of the information within. Trust me this book contains a bible's worth of information and I'm just listing it because it is a good book that can be used as reference even when you become a coding ninja.

-- Head First JavaScript programming: Now this is more of a beginners book, this book has a unique way of teaching you how to code and then making sure you actually understand what you are reading. It also comes with fun exercises that you can try out yourself to make sure you have a proper grasp on things.

-- Head First HTML 5 programming: forget the fancy name, this is really a JavaScript book that introduces and teaches you how t use the latest Html 5 features to your greatest advantage while teaching you valuable Javascript at the same time. It's win - win for you.

-- JavaScript and jQuery: the missing manual: Like the name, this book is the manual that should have come with Javascript. The book does a fine job of introducing you to the basic concepts of Javascript before moving on to teaching you how to use the most popular Javascript library, jQuery to build web apps. NOTE: make sure you have a proper understanding of Javascript before disturbing yourself with any library

If there are other good books, please mention them in your comments.

* Get yourself familiarized with the browser console because this is where you will be debugging your codes while learning. You should also get the firebug extension for browsers. It is lightweight but very powerful.

* For editing your codes, a text editor would do just fine additionally, you can get the Jseditor created by our very own Dhtml.

* Read more books and practice like your life depended on it

* Finally, Build something. It doesn't matter how small or how big, just build something that you can be proud of. Learn to always push yourself and try to do those things that scare you the most.

* After this, you can move on to learning a library of your choice. It's not always a good thing to reinvent the wheel, raw Javascript is great and all that but there are still a lot of cross browser incompatibilities what with your codes behaving differently in different browsers or not working all together, this is where libraries come in to handle all the wahala for you so that you can focus on the important thing building awesome web apps

Note that apart from jQuery, there are still other libraries that offer the same functionalities but I don't think you will be needing all of them, just stick with the one that is most convenient for you. When you head don come dey hot, you can add more to your skillset.

Also note that Javascript can be used for server side programming as well so you might not need to learn additional languages once you master Javascript. That's all for now folks.

Let's get coding!!

First of all, for those of us who are still unsure of what this thread is all about or just miss it generally; while creating this thread, all I had in mind was just to rub minds with fellow novice programmers who are just getting to learn javascript, share ideas and educate each other.

That's the basic idea.

If while doing that we get to build amazing apps that will increase our passion and greed then fine but this is just a thread for seekers of knowledge.

Okay, we have derailed well enough. Davidsmith, thanks for increasing the count of this thread.
