Referring to ECMAScript 5 compatibility table page, Firefox 4 - 6 and Chrome 13 - 14 are the most compatible browsers.
The Mozilla JavaScript Reference might be the closest. See its entry for ECMAScript5 support for details.
Update (2011-08-05)
It appears that ES5 is backward compatible with ES3 (1, 2). The only way to break the compatibility is to use "use strict" to enable a subset of ES5 deemed as less error prone.

JavaScript - Wikipedia
3 weeks ago - JavaScript is a high-level, often just-in-time–compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles.

In Node.js the new ECMAScript standards can be used without problems, as you don't have to wait for all your users to update their browsers - you are in charge of deciding which ECMAScript version to use by changing the Node.js version, and you can also enable specific experimental features by running Node.js with flags.

May 22, 2026 - Classes are a template for creating objects. They encapsulate data with code to work on that data. Classes in JS are built on prototypes but also have some syntax and semantics that are unique to classes.
