Suck on Codecademy

[NerdNinja]

So here is the code so far.

I keep getting a syntax error. also sometimes I'll change one thing and it will say numHours is not defined and codecademy says I passed.

If you tell me what's wrong please EXPLAIN WHY!!!! I still want to learn!

 

Thanks in advance!

why is there a semicolon next to the bracket at the very top? I'm just learning java but I'm pretty sure you shouldn't do that.

Look at line 4 in your code. You put a curly brace before the content of the function, which closed it, and then you put a semicolon, which you don't need after a curly brace anyway.

I removed line 4 and line three becomes broken

it's not necessary but doesn't change anything. I put it there so the little i doesn't pop up in front of the line

I believe everything from 'if...' up to but not including 'sleepcheck(8)' (lines 5-10) needs to be inside the curly braces on lines 3 and 4.

the instruction also say to 'return' the statements not console.log() them

it's javascript, but you are right the semicolon is not needed

put a brace on line 11 and move the current contents of line 11 to a new line. You have opening and closing braces for the if and else, but if you just delete line 4 then you have no closing brace for the function.

 

I'm more familiar with Java and Python than Javascript, so I'm sorry if I'm incorrect. My general knowledge makes me think that's the problem though.

ok now I get this(sorry for the large pics. Taking screenshots on a cromebook)

it should be if (numHours >= 8)

[CornOnJacob]

Here is my code if you want to see something that should theoretically work:

//Write your function below. //Don't forget to call your function!var sleepCheck = function(numHours) {    if (numHours >= 8){	return("You're getting plenty of sleep! Maybe even too much!");    } else {	return("Get some more shut eye!");    }};sleepCheck(10);sleepCheck(5);sleepCheck(8);

Ok so that worked. Now I wan't to know why this worked and mine didn't.

It's possible JS is anal about spacing. I seem to recall that being an issue in the past.

if (num<=10){

won't work, but

if (num<=10) {

would. Same goes for spacing after else. "else{" might not work, whereas "else {" would.

 

I think.

Remove the ';' from the end of the if statement. It is not needed.

read this post without any of the assumptions/knowledge gained from other posts.

 

1.  you start the 'sleepcheck' function on line 3 and end it on line 4.  the function is empty and literally does nothing.

 

2.  on line 5, you ask a FUNCTION what number it is.  this is a logical issue; you can only ask numbers what number they are.

 

 

this probably won't answer your questions, but if i just gave you all the detailed answers; you probably wouldn't learn anything either.  try asking questions one step at a time.

 

EDIT: 

 

the accepted answer is wrong.  return is a keyword, NOT a function.  there should not be ()s for the 'return' statement.

 

EDIT2:

 

i should clarify what i mean by wrong.  i'm not saying it doesn't work; i'm saying it's not needed, provides NO benefit, will harm your future learning, is NOT standard, and is unnecessarily confusing.  try it without it.

 

also, how are you expected to test your code?  nothing is being outputted.

 

EDIT3:

 

js is very largely space insensitive, especially when you use semicolons correctly.

Starting on line 4, you put:

if (sleepCheck>=8){    console.log("stuff");} else {    console.log("other stuff");}

Two problems here:

1. The big one is that you have sleepCheck where numHours should be. You want to compare the value of a variable (number of hours of sleep) to 8, but instead you are comparing a function, and on top of that, you are inside the function that you're referencing.
2. Replace console.log() with return. You want your function to return something. You could console.log() the text and return 0 in a normal program, but Codecademy asks specifically for you to "return" your answer.

That's all I can find right now. If it still doesn't work then let me know

 why do you keep saying return is a function?

 

what language are you used to where return is a function?

I didn't think I ever said that return was a function, just that every function should return some value.

[tbc]

you're saying it's a function because you call it like a function.

[rashdanml]

Minor technicality tbh, don't make such a big deal out of it. 

[CornOnJacob]

"return()" vs "return". I just put the parentheses because if you're returning a string, you need them for return.

No you don't.

[CornOnJacob]

No you don't.

Ok, then you don't need to. It didn't throw an error in my code above, and I prefer to use parentheses whenever I can (it groups things and makes it easier for me to understand both code and math). I haven't actually used JS in a while so you'll have to forgive minor syntax errors or things I've carried over from other languages.

[tbc]

that's all i'm saying.  an ounce of prevention is worth 2.4 metric tons of cure when you're learning.  I'm not trying to call you stupid; I just don't see why we should teach people the wrong thing when the correct answer is EASIER and better to do.

 

EDIT:

 

js almost never throws errors.  it's actually quite hard.
