On: Actual drawbacks to omitting semi-colons?

[zmmmmm]

The one place where this really bites me is return statements. For example:

    function x() {
       return 
    	   2+3;
    }
    alert(x());

Every now and then I'll reformat a line by breaking it in two and it takes me 10 minutes to figure out why my code is not working.

damn it I forgot that - does anyone know how to make vim highlight this?

In your after/syntax/javascript.vim:

    syntax match javascriptReturnError /return\s*\n\r\?\s*\w.*$/

    ...

    highlight link javascriptReturnError Error

Obviously you can play around with the regex to tweak what matches.
