“JavaScript templating refers to the client side data binding method implemented with the JavaScript language.

WHAT IS JAVASCRIPT TEMPLATING?

WHY TO USE JAVASCRIPT TEMPLATING?Just think about it.

Wouldn’t it be better and fast if just raw data like in JSON format is sent from server and display it in HTML on the client side?

Andthat pain in appending data in HTML!!

How about reducing this pain?

PROS:➤ Data generation is separate from presentation code, so good code

organization➤ Web server load is reduced➤ Output generation is more expressive (template syntax doesn't require a

sea of string concatenation)➤ Working with Web Designers

CONS:➤ Users with JavaScript disabled, will very likely not be able to use it.➤ Search Engines will not be able to index your page.➤ Not widely used and well documented for WordPress
