Always, Always Use Semicolons.
If you not use ;(semicolon) in the code, it's very difficult to find the error.
So please try to use everystatement with semi colon.
var someItem = 'some string'
function doSomething() {
return 'something'
}
Better
var someItem = 'some string';
function doSomething() {
return 'something';
}
