What is the Purpose of `` in Backbone.js?

Demystifying

In the realm of web development, encountering unfamiliar code can be intriguing. The use of in the source code of Backbone.js's TODO example has piqued curiosity. Let's delve into its purpose.

The construct is a technique employed to introduce templating capabilities, akin to those found in server-side languages like PHP, but implemented within the client-side JavaScript environment.

When setting the type attribute to "text/template," the browser no longer treats the script content as executable code but rather as raw text. This allows developers to include within these script tags any content they desire, such as HTML and dynamic data, which can later be utilized by a suitable templating library.

Each library possesses its unique template syntax, enabling developers to define templates within the

Through this mechanism, web applications can leverage the power of templating to generate dynamic HTML snippets on the client-side, allowing for the efficient and flexible construction of web pages, particularly when working with data that requires real-time updates or manipulation.
