Ayman Hourieh covers some interesting manipulation of Arrays that accommodates typical data structures. He also covers how to bind methods to objects, sorting with custom functions. He shows a custom AssertException, and covers using Firebug for debugging. He covers some JavaScript quirks: static local variables, null, undefined and delete.
Ivo Wetzel covers some of the quirks of the JavaScript language. Some of these cause subtle bugs, some overturn conventional wisdom. It covers toString on numbers. Covers the advanced JavaScript features such as prototypal inheritance, this, closures, anonymous wrappers, type-casting, automatic semicolon insertion and hoisting of function and variable declarations.
Based on Simon Willison's original 2005 eTech talk, Simon expands this into a full article covering the expressive functionality of JavaScript. He covers the basics of JavaScript: literals, variables, functions, scope, control flow, objects, classes, inner functions and closures. Everything a developer needs to know before diving into more advanced JavaScript.
Jim Ley covers the intricacies of type conversion, implicit and explicit. He covers type conversion into boolean, string, number, undefined, null; and parsing into floats and integers. This is backed up by conversion tables for quick reference. There's also a useful section on regular expressions for form field validation.
First in a series of talks from Douglas Crockford about the JavaScript language. These talks cover the JavaScript language, from the history, the language, advanced features, platforms, standards and programming style. Talks about inheritance, using functions to build objects, closures, as well as the basic JavaScript syntax. Also covers code conventions. JavaScript is a language that requires discipline.
A collection of performance related techniques, including temporary references (for deeply namespaced properties), optimising loops by referencing the collection length once, reasons to avoid the with syntax, using null over the delete function, comparison for equality and identity and short-circuit logical expressions
