How do I fix unexpected token ' { '

Question

I was creating a function in JavaScript and the page wouldn't run the code but instead said there was an unexpected token.
function myFunction {
var x=document.getElementById("my law")
document.getElementById("demo").innerHTML
}

Answer 1

After "myFunction" you need parentheses as such:

function myFunction (){
/ / stuff
}

You need the parentheses even if you have no parameters. Hope I helped!

Answer 2

I prefer not to leave out ; semicolons where experts recommend to use them even if the script works without them. For readability and for preventing introduction of bugs by mistake.
Here's a very nice article about code conventions for JavaScript by Douglas Crockford (JSON):

Answer 3

thx for the article, I appreciate it, I'll look over it :D

Answer 4

And you missed the semicolon

Answer 5

In my experience, semicolons in javascript didn't matter.

Answer 6

@Cocoa But they're extremely recommended

Answer 7

I suppose, I'll credit you that, it'll work either way so whatever haha :D

Answer 8

@ Cocoa, will 'var x = 5' work in a browser that doesn't support ECMAscript6?
