Better Coding Standards in JavaScript 5

“ECMAScript 5, or JavaScript 5, was released this week. The new
version improves the basic libraries and introduces stricter
runtime modes to improve the general standard of Javascript coding
by identifying and removing common coding errors. What this means
to you is that certain parts of your JavaScript code will have to
be rewritten to compensate for the new changes, should you have
fallen into the “weak coding” trap we as developers are always so
susceptible to.

“We all know that JavaScript 4 was a White Elephant: ECMA didn’t
even release a version 4 specification owing to different groups
being unhappy at the developments; and as such, no browsers support
it. For some reason Adobe’s ActionScript is based on the proposed
changes, although it is rather unclear why they bothered.

“Recently there have been rather large improvements in
JavaScript engines like Nitro and TraceMonkey, making JavaScript
usable to the point that even Google Wave are exploring the way
forward with online applications. Another extension from the
Internet Giant’s browser, that was released as part of GWT 2.0 and
called Speed Tracer, helps optimize the performance of JavaScript
Applications.”
