	== What is JavaScript? ==		== What is JavaScript? ==

	JavaScript is a scripting language widely used for client-side web development. It is also known ~~by a number of other names including~~ ECMAScript, and ~~JScript (these are all the same thing but exist due to issues~~ over the ~~licensing of these names)~~.		JavaScript is a scripting language widely used for client-side web development. It is also known as ECMAScript and has been progressively improved over the years.

	~~If you have~~ a ~~spare 27 minutes~~ and ~~would like a quick background on~~ JavaScript ~~and it's origins, see this video from Douglas Crockford '[http://www.youtube~~.~~com~~/~~watch?v=gz7KL7ZirZc JSeverywhere: Douglas Crockford - JavaScript, The World's Most Misunderstood Language]'~~.		Since Moodle 3.8 we recommend the use of Native JavaScript rather than through a library such as jQuery or YUI, and require that all new JavaScript be written in the style of ES 2015 modules. These should be placed in the amd/src directory of a component and are transpiled at development time to be compatable with a wide range of browsers.

	~~== What does AJAX mean? ==~~
	~~AJAX means "Asynchronous JavaScript and XML". It is a group of interrelated web development techniques used to create interactive web applications or rich Internet applications.~~
	Although XML is included in the acronym, AJAX is not a single technology but a group of technologies. In reality with modern JS, this tends to be JSON which is much more lightweight and easy to produce in PHP than XML.

	~~See [http://en.wikipedia.org/wiki/Ajax_(programming) AJAX (Wikipedia)] for general information and [[AJAX]] for information on AJAX and Moodle.~~
