{{Short description|Client side data binding method implemented with JavaScript}}
{{no footnotes|date=July 2013}}

'''JavaScript templating''' refers to the [[client side]] [[data binding]] method implemented with the [[JavaScript|JavaScript language]]. This approach became popular thanks to JavaScript's increased use, its increase in client processing capabilities, and the trend to outsource computations to the client's web browser. Popular JavaScript templating libraries are [[AngularJS]], [[Backbone.js]], [[Ember.js]], [[Handlebars.js]], [[JSX (JavaScript)|JSX]] (used by [[React (JavaScript library)|React]]), [[Vue.js]] and [[Mustache.js]]. A frequent practice is to use double [[curly bracket]]s (i.e. <nowiki>{{key}}</nowiki>) to call values of the given key from data files, often [[JSON]] objects.

== Examples ==
All examples use an external file <code>presidents.json</code> with following contents
<syntaxhighlight lang="javascript">
{
"presidents" : [
{ "name": "Washington", "firstname": "George", "born": "1732", "death": "1799" },
{ "name": "Lincoln", "firstname": "Abraham", "born": "1809", "death": "1865" }
]
}
</syntaxhighlight>

All examples will produce the following HTML [[Unordered list|list]]:

* Washington (1732–1799)
* Lincoln (1809–1865)

➊ Load the necessary resources, including required [[jQuery]]<br />
➋ The HTML code with <code>template</code> attribute marking for-each subtemplate and <code>z-var</code> replacement instructions.<br />
➌ Load JSON data from <code>presidents.json</code> and apply data to the HTML template with id attribute "<code>target</code>".

➊ Load the necessary libraries, here [[mustache.js]] and [[jQuery]]<br />
➋ The HTML code provides a "target" to insert generated contents into.<br />
➌ Provide a template named "president-template". <br />
➍ Last is a function grasping the JSON data, and for each president's subitem, grasping one template and filling it to finally select the HTML page's target appending the whole to it.

Templating becomes useful when the information distributed may change, is too large to be maintained in various HTML pages by available human resources and not large enough to require heavier server-side templating.
