What are the best AJAX development tools?

Question

Hi there, can anyone please help me to identify the best AJAX development IDE or tools base on the advantages and disadvantages? Thank you

Answer 1

I like too much Aptana Studio.

Answer 2

For the "tools" part of your question, I have found the following combo quite good:

Firefox + Firebug + FireQuery + FireRainbow + PageSpeed + Web Developer

Answer 3

Have a look at the up-coming WebStorm from Jetbrains.

Upsides: Support for Javascript and extended frameworks, such as YUI, JQuery, Dojo and Prototype; code completion, refactoring and code inspection. Mozilla-based Javascript debugger

From the help file:

Smart, DOM-based, browser-type aware JavaScript code completion for: Keywords, labels, variables, parameters and functions. User defined and built-in JavaScript functions. JavaScript namespaces. JavaScript and AJAX error and syntax highlighting. JavaScript and AJAX-aware refactorings: Rename a file, function, variable, parameter, or label (both directly and via references). Move/Copy a file. Safe Delete a file. Extract inlined script from HTML to a JS file. Extract function. Numerous JavaScript and AJAX-aware code inspections and quick-fixes. JavaScript and AJAX Intention Actions that let create various application elements. JavaScript and AJAX code formatting and folding. JavaScript and AJAX code blocks, live

Downside: Not free and not yet released (there's a 45 day trial on the Jetbrains website)
