A single line of JavaScript is what powers a lot of blogging technologies these days. Widgets, sharing tools, visitors tracking, advertisers. In many cases a single line of JavaScript is all that a blogger needs to add a new technology to their blog. The problem is what happens when a lot of these single lines of JavaScript come together...

Optimization of several CSS and JS files

Well, when I say solved I mean solved for the two most important browsers - Internet Explorer and Mozilla/Firefox. Still that’s good enough isn’t it?

What with the fact that optimising Sylvester for speed is causing its brief, legible internals to balloon into reams of hard-coded arrays and unrolled loops, and the fact the fact that Prototype’s latest release has put on a few extra chins (1.5.1 is 97kb compared to 1.5.0’s 70kb), I thought it was about time I figured out how to serve my JavaScript like a grown-up. Most of what’s written online seems to be focused on specific platforms (PHP, mostly) and I thought something a little more generally useful was needed.

Какой же метод минимизации (minify) следует использовать для архивирования Java Script?

Javascript is becoming increasingly popular on websites, from loading dynamic data via AJAX to adding special effects to your page.

Unfortunately, these features come at a price: you must often rely on heavy Javascript libraries that can add dozens or even hundreds of kilobytes to your page.

Users hate waiting, so here are a few techniques you can use to trim down your sites.

I’m happy people are finding the article on javascript optimization useful. But I made a giant, horrible mistake. A mistake that befalls many tutorials.

The next generation of web apps make heavy use of JavaScript and CSS. We’ll show you how to make those apps responsive and quick.

External JavaScript files block downloads and hurt your page performance, but there is an easy way to work around this problem: use dynamic scripts tags and load scripts in parallel, improving the page loading speed and the user experience.

When scripts are loaded the normal way they block all other downloads in the page and any elements below the script are blocked from rendering. Loading scripts asynchronously avoids this blocking behavior resulting in a faster loading page.

После заметки Стыкуем асинхронные скрипты и предложенного решения от Steve Souders я подумал о модульной загрузке какого-то сложного JavaScript-приложения. И понял, что предложенный подход в таком случае будет довольно громоздким: нам нужно будет в конец каждого модуля вставлять загрузчик следующих модулей. А если нам на разных страницах требуются различные наборы модулей и разная логика их загрузки? Тупик?
