whats a good tool for finding syntax errors in my javascript code?

Question

I'm trying to use firebug to walk through my code, but there's a syntax error somewhere and firebug is struggling with it. Are there any good tools that will scan my javascript for sytax errors?

Thanks in advance for your help!

Answer 1

JSLint, the best!

Answer 2

googled, find this interesting tool, I haven't personally used it, but from the screenshot, it seems be able to catch the error.

I use Visual Studio 2008 to write my javascript, it has intellisense, so vs will work for you if you have that.

Answer 3

I find that the error console in Firefox is the easiest way to locate errors in JavaScript. I asked a question about equivalents for other browsers but I haven't found anything as simple and easy to understand as Firefox's error console in other browsers, so even if I am using Google Chrome (my main browser) I often start Firefox in order to get the error console.

Google has a JavaScript compiler. Maybe it will find the issue for you.

Answer 5

I use JSLint, but Aptana and NetBeans (and some other) editors include syntax checkers that find problems as you type. As a result, I pretty much never have any syntax errors for JSLint to find. JSLint, of course, finds other problems.

• JSLint is the gold standard
• JavaScript Lint is very nice, too.
