Try Ruby: learn the basics of the Ruby language in your browser. JavaScript Garden. Although JavaScript deals fine with the syntax of two matching curly braces for blocks, it does not support block scope; hence, all that is left in the language is function scope. function test() { // a scope for(var i = 0; i < 10; i++) { // not a scope // count } console.log(i); // 10} There are also no distinct namespaces in JavaScript, which means that everything gets defined in one globally shared namespace.
Each time a variable is referenced, JavaScript will traverse upwards through all the scopes until it finds it. In the case that it reaches the global scope and still has not found the requested name, it will raise a ReferenceError. The Bane of Global Variables // script Afoo = '42'; // script Bvar foo = '42' The above two scripts do not have the same effect. Again, that is not at all the same effect: not using var can have major implications. // global scopevar foo = 42;function test() { // local scope foo = 21;}test();foo; // 21 Local Variables var foo = 3; bar = 4;}test(10); Hoisting.

Getting Started With Pattern Libraries. Three weeks ago, A List Apart went open source. The markup on the website is something I feel very close to. Over the years, if I’ve been unsure of how to mark something up, I’ve often referenced the HTML on A List Apart to see how it’s been done there because I know the people who work on it really care about semantics. Uncertain of how I could help, I suggested to the team that A List Apart have its own pattern library.
Pattern libraries are something I do a lot for client projects and I thought the site could really benefit from one. It’s a technique I first saw former Clearlefty Natalie Downe develop for client projects back in 2009, and has been used by Clearleft as a front-end deliverable since. A couple of days later, with some help from Mat “Wilto” Marquis, we had a repository for the pattern library up and running complete with a live preview. Features of A List Apart’s pattern library#section1 By breaking the site up into patterns, it’s easier to find those bits of markup. Twist Style Friday: Piscataqua.

I love every last one of you, friends! " It totally disarmed me. Phew. Garter edges, pretty cables, and a hood.

The Absolute Beginner's Guide to Sass. What is Sass? Sass stands for Syntactically Awesome Stylesheets Sass, and was created by Hampton Catlin. It’s a way to simplify your CSS workflow, making development and maintenance tasks easier. For instance, have you ever had to do a find-and-replace in your stylesheet to change a particular HEX color for a particular indecisive client? Or had to open up the calculator app to figure out a column width in a multi-column design? Sass introduces new concepts such as variables, mixins, nestings and selector inheritance.
Sass looks similar to CSS, but without the semi-colons and curly braces. Given the following CSS: You’d write the following in Sass: #skyscraper_ad display: block width: 120px height: 600px #leaderboard_ad display: block width: 728px height: 90px Sass uses two-space indentations to define code nesting.
