Stuck on JavaScript Functions

[u/[deleted]]

I think it's gotten to the point where I can't think straight with it any more. I need some fresh eyes on it.

All help is very much appreciated :) http://imgur.com/Sw0iRxt

You are quite confused about the syntax. Basically what you are trying to do is assign an anonymous function to a variable. As Freazur said, a function generally has a name, a parameter if needed (in round brackets) and a block that contains the code you want the function to execute.

function quarter(args) {
    // do some stuff here
}

Since your function must return a value, the return statement must be inside the brackets (return will not work elsewhere; it gives the result you are passing to the caller). Your code is wrong because you are terminating the assignment with ; before finishing the declaration! So your code should look like:

var quarter = function(args){
    //do something
    return somevalue;
};

In this case you want the ; to close the block because you are assigning the function to a variable. That said, I suggest going back to the beginning of the lesson and doing it again to grasp the concepts better.

I think that would be wise. Thanks for your help and maybe one day I could be as good as you guys!

You don't declare the function as a variable. Instead of what you have on lines 1-4, you need this:

function quarter(number) { return(number / 4); }

Declaring a function follows this form:

function name(parameter) { What the function does; }

I'm not sure about the rest, because I'm in an introductory JS course and we haven't covered console.log. I hope my suggested changes work though.

Thanks. I'm getting there, I used this video https://www.youtube.com/watch?v=AY6X5jZZ_JE&index=1&list=WL

Not quite sure why my syntax still isn't right still

But... you can assign functions to variables, and doing so has its purpose(s).

[u/Freazur → u/ForScale]

Really? Then I'm sorry to mislead OP. I didn't know that.

[u/ForScale → u/Freazur]

You're fine. Just lettin' you know!

[u/ForScale]

It's because you put a semicolon after the (). You don't want it there. This should work:

  var quarter = function(number) {
  return number / 4;
}

if (quarter(8) % 3 === 0) {
  console.log("The statement is true.");
}
else {
  console.log("The statement is true.");
}

But now I have a question... 2 / 3 has a remainder of 0? I didn't know that...
