More Firefox Tools for Checking JavaScript Syntax?

Question

Not sure if there is any additional Firefox tool for checking JavaScript syntax, var declaration or even precompilation?

I found it very difficult to debug JavaScript in an html webpage. I have to add a script there. When scripts become very large or long, it stops working. In principle, there should be some errors. This is very unpleasant, even stopping the load. I need good tools to learn about bugs.

I tried FireBug. This is good, but not enough. Perhaps I do not know all its features. Anyway, I need some good suggestions.

Hi Gene: you can change one option.maxerr variable inside your jslint.js file to the number you need.

The default value is 50, you can change it to 500 or 1000 to suit your taste.

Answer 10

I use the following values ​​to verify the code.

• JSHint @ http://jshint.com
• JSLint FF plugin. Get https://addons.mozilla.org/en-us/firefox/addon/jslinter/

Alternatively, jshint and jslint plugins are available for text editors such as Notepad ++, sublime, etc.
