Hi, I am Wi5trone. A newly admitted medical student of UI. I am also a JavaScript lover(tho still learning). I did this simple GPA calc last night. It accepts all your details(name,department, courses, scores) and alerts you with your full details together with your GPA.

Good innovation. �

You be Baba. I'm also a javascript beginner but I must say, you really tried from my beginners perspective

Great one bro. Really nice don't let med school take this away from you o.

i downloaded ur app and looked at the source code. Your logic is correct but ur code needs fine tuning. Obviously, one can see that u r still new to this by glancing at your code. Areas tht need attention are: 1) code repetition. This is inefficient and a big no no in sofware engineering.
The code to determine d CLASS of grade was repeated tediously throughout the program for variables 'a','b' and 'c' through 'h'!

 
if (0<=a && a<39)
   {var p1= 1}

You could have encapsulated the logic in an object and used it over and over without needing to repeat yourself.
DRY (Dont Repeat yourself) principle. Learn this principle.
2) some computations were redundant.
E.g first class is any gpa above 4.49 or above or equals to 4.5,so there's no need checking d upper bound, just check the lower bound.
I.e

 if(cgpa> 4.49) 
 or
 if(cgpa>= 4.5)

by not checking d upper bound,you save computation cycles. Same applies for checking upperbound of points in d A range. Ofcourse to avoid erroneous input,you would check that data entered is in the right range. Between 0 - 100.
3) Lastly,your way of checking comparisons,though correct nd logical would b unnatural to most ppl.
You can stick with it,if it's natural to you but typical norm is to place the literal on the right of d variable being compared.

 if(0<=e) 
 

Unnatural.

 if(e>=0) 

. Natural. I suggest u adopt the Natural form,it's easier to read.

@asalimpo

Your DRY advice is highly useful. However, another tenet of programming is "Avoid premature optimizations."

Clock cycles, DRY, encapsulation... Are too many balls to pursue for a beginner.

I'll admit, this below looks great.

if(cgpa> 4.49)
or
if(cgpa>= 4.5)


He's already done one thing most programmers have problem with - shipping.

He's shipped i.e. Published his code for others to see.

My unsolicited advice to @Wi5trone kudos. Fretting about how your code looks right now is futile. No, it's guaranteed to make you quit.

So build more stuff. Target 5 more mini programs like this and publish them here.

After that come back to this one and see if you can improve it. You might have to rewrite it from scratch and that's fine.

Again kudos. If you ever need practical udemy videos. My number's in my signature.

nice one....I also did something similar with python last year...it was cool though...

and by the way am I expected to give the total units or scores my self for the calculator to work? or do I need to fill all the boxes for the app to work cos I got an error when I tried using it...I tried just 4 courses tho...

Nice one, however try and learn more on arrays. You can do wonders with arrays.

Also, do allow student to select number of courses they want to calculate. Thanks
