I have a JS file where no matter what is placed on the first line (comment or code), PHPStorm generates a syntax error. When I hang over the error, the description says "Expected Expression." What does it look like:

You have a signature of the UTF-8 specification ( EF BB BF ) immediately before the line var myApp= (first line of code in this file)

If you delete it, the IDE will stop complaining.

In most cases, this problem occurs due to copying. There may be some characters / line that may need to be rewritten in your IDE.

In such cases, just copy your code into notepad and copy it back into your IDE again.
