What would be the output of the code below

>> since n is not equal to 1
>> return 3 * 2;
>> 6

>> since n is not equal to 1
>> return 3 * 2;
>> 6

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.

what's funny?

Ok

>> since n is not equal to 1

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

Ok, I'll advice you practice functions on freecodecamp. Do all the the JavaScript if you can.

> The function 'ftl' takes an input 'n'
> n is given as 3 from the console.log(ftl(3));

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

> ^^^ So the function states if n is exactly equals to 1 (type and value denoted with (===), the function should return 1 (the if statement)

if (n === 1) {
  return 1;
}

> But unfortunately, the number is greater than 1 so the function will skip to the next statement.

> Which is since n is not equal to 1,

return n * ftl(n - 1);

> Remember n is given as 3, so just replace n with 3.

> So it will be:

return 3 * ftl(3 - 1);

return 3 * ftl(2);

> What's really happening is that the function is calling itself within it self, More like a pregnant mother with a featous of herself (if that makes sense, doesn't really represent recursion but that's one way to look at it)

> Now function ftl(2) on the right when called will return 2

return 3 * 2;

> Finally it will be

6

Your code will give a stack overflow error without the if statement. It is called the base case of a recursive function.

Like God damn!!!...then @op, you were the one that dropped "variable chaining" stuff some days ago. Why not stick to the basics for now, before moving to the advanced.

Basics are important and freecodecamp covers all that, I don't think I Know advance stuffs and I'm good to go. I spent a lot of time with the basics.

Recursion is actually basic, just like loops, especially in functional programming languages.

I'll assume you're trying to learn recursion, It may take a while before you get used to recursion, and if you've already learned about loops, it gets worse.
You're best bet is a pen and paper or visual debugger to step through a recursive code.

Classical recursive solution for the Factorial function.

JS programmers do you guys use === for equality? I had assumed that == was the standard for equality in modern Programming languages. That's aside from := which PASCAL used

== in JavaScript is used for comparing two variables, but it ignores the datatype of variable. === is used for comparing two variables, but this operator also checks datatype and compares two values.

As such.

2==2? true
2=="2" true

2==="2"? false
2===2? true

=== Is used to also check variable types. == Is used for just equality.

Something like 5 == '5' will return true but false for the triple equal

I wasn't referring to you though. You can see I @op

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

@Tensazangetsu20 and @GreatIgboman

Thanks for the explanation. Now I hate all these loosely typed languages more. Why for God's sake will int=string ever be true on earth?

Java has it too and it's strongly typed.

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

Purely my own opinion but also make research and come up with what you want too

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

The code up there is based on condition.
If n equals 1, output 1
If n is not equals 1
Return
n*func(n-1)

Then u gave a value for n, which is 3. Anywhere that n is in the code, it will substitute it for 3.
3* func(3-1) =6

Java even has var now that lets you write variables without declaring their types. It used to be just == and equals()
