One way of emitting events is by using trigger on a jQuery element.

Streaming Consistency

Since Node's streaming Api is still changing and is in 'unstable' category, writing a npm module using streams may cause some unexpected behaviors on older versions of Node. To ensure that streams are compatible with older versions of Node, a drop-in replacement for stream is available called 'readable-stream'.

Line by Line

There are many streaming modules on npm to read lines from text files, but many are inaccurate and slow. Inaccurate means that there is a failure to read many lines and slow means that files with a lot of text per line will cause the modules to crawl.

No nodejs required

Many times there are code samples on Github that have simple static files that you would want to run on a server, such as the case if there are ajax calls in javascript files.

Sprites are often used to stylize 'a' tags. When a sprite sheet is used, a fixed width and height is used to specific the image on the sprite.

Off with the Rule

Most of the time, css rules are overridden to get a different style, but some rules need to be outright removed. For example, if a hover effect is in place when javascript is disabled, but the rule might interfere with the javascript code when javascript is enabled. This might happen when using a jQuery plugin for menu creation or text effect.

Checking Visibility

// Visibility Test Cases

$("#word").is(":visible");
$("#word:visible").length == 1;
$("#word:visible").length > 0;
$("#word").css("display") == "block";
$("#word").is(":not(:hidden)");
!$("#word").is(":hidden");
