This is news to me! I really need to get to speed with all the new additions in these programming languages

Actually this isn't valid in java even with the inclusion of car in java 10. You have just equals and == but apex has it. It's pretty much an extension of java and used in Salesforce development.

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/langCon_apex_expressions_operators_understanding.htm


I always thought java had that as I have used that a lot in Apex which is also strongly typed.

I was only supporting your point though so the op can see it's impossible to skip the basics

ooh my bad..I was half-sleepy

good morning boss

tensazangetsu20:
Java has it too and it's strongly typed.

Since when did java have triple equal to?

Oh I see you corrected yourself up there

sixpathsofpain:
and please bro, what's the use of the first if and return statement? because I don't see any need for them

The first “if” is a validation of the input so a user doesn’t enter 1 as a value.

No worry. I go holla you as soon as I reach GIG

Not correct. It's not validating the user Input. It's checking for the "Base Case" for the factorial function. If the user enters 1 as input, 1!=1 and the if will correctly return 1 as the factorial of 1. This function requires some knowledge of the factorial function to understand what it is doing. Basically n! is equal to n*(n-1)!. That is 5! for example is equal to 5*4!. 5!=5*4*3*2*1 and 4!=4*3*2*1 so 5! Is 5 times 4!

Lols...it's actually not this complicated jeez.
This should be the most complicated answer to the most basic question ever.

It shows you yourself don't understand what's happening there

sixpathsofpain:
bro thanks for your explanation. It really helped me alot. I'm beginning to rap my head around recursions little by little but I know this I going to take time mehn but I know I wouldn't give up no matter how long it takes, I can't just stop going back to try and figure it out
Please I need your advice on something. I feel you're one of the few reasonable and matured one's on this thread..
Please the reason I wanted to learn JAVASCRIPT in the first place was because I want to become a full-stack web developer. And I just jumped in JavaScript straight on. after sometime and a few research, I found out I needed to learn HTML and CSS first before JavaScript and then react (I don't know what any of them does cause I'm a noob ) so now I'm planning on quitting JAVASCRIPT for now, to go focus on HTML first then CSS before continuing JAVASCRIPT and then what ever should follow (for me to become full-stack) would you advise me to quit JavaScript now and go focus on those (HTML and CSS) or I can continue with JAVASCRIPT before HTML and CSS?

And please just help me give an outline of how my learning path should be to become full-stack ( because I don't like starting what I don't Finnish )
Thanks

@tensazangetsu20
please you too can help me contribute

You can actually learn HTML5 and JavaScript side by side.

You just have to create a time table. Say 2 hrs for each paper day. It's possible. Just don't overthink what you don't get ask questions.

If you know you can't take all together then take it one by one from html, css and JS.

For CSS focus on layout with flex-box or CSS grid (refer to this post when you get there).

Learn CSS very well before moving to other libraries.

Take it easy on yourself.

For outline, visit freecodecamp(dot)org

Very wordy, yes. But it's a basic straight forward recursive solution of factorial function. Calls itself each time reducing the input to the function by one. Until it gets to the vase case of 1 and then like a stack, "pops" every previous call. Na textbook stuff. Maybe my previous explanation was too convoluted, but this function is too basic for me not to know

It's basically the first thing everyone learns when learning recursion.

Thanks alot bro. Really appreciate. Just one question others libraries like ? PHP ? Or what

Other CSS libraries like Bootstrap.

Also same with JavaScript, master and learn the basics very well before jumping to libraries like React.

PHP is a programming language like JavaScript.

Bro may God almighty continue to bless you for people like us. Please just a few more question I'd like to ask( lastest, I promise )

1.) Do you suggest I change OS from WINDOWS to LINUX ( to prevent unnecessary crashing since Linux is more light weight)
2.) Should I create a github account or repo now or when I'm ready to start building projects
3.) Like how long would it take me to become a junior full-stack developer if I studied seriously for 5 hours minimum a day ? Im thinking maybe after 1year and five months..

1) Windows is fine

2) Yes learn git and GitHub early

3) It depends on you. Set your timeframe.

jbreezy:
Op doesn't even have a solid knowledge of function yet.

Oh, I see. Op should do due diligence to the basics first.

Recursive
3 X 2 X 1

sixpathsofpain:
honestly bro please if you can just help me do a little explanation, I'd really appreciate because function declaration and recursions are confusing me seriously. I don't even know where you got 2 from to multiply it by 3.

that n is 3 and n - 1 = 2

sixpathsofpain:
and please bro, what's the use of the first if and return statement? because I don't see any need for them

if the first 'if' condition isn't there, ftl(1) will return 0. whereas, even the factorial of zero is 1. That if condition alone doesn't even make that solution correct, because ftl(0) will return zero instead of 1.
