How do I fix unexpected token ' { '

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 }

After "myFunction" you need parentheses as such: function myFunction (){ / / stuff } You need the parentheses even if you have no parameters. Hope I helped!

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): javascript.crockford.com/code.html

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

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