JavaScript templating refers to the client side data binding method implemented with the 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 (used by React), Vue.js and Mustache.js.
