RJS (Ruby JavaScript) is a feature in Ruby on Rails that allows you to generate JavaScript code dynamically from your Ruby code. The main purpose of RJS is to simplify the process of creating AJAX-based interactions within your Rails application.
Here are some key purposes of RJS in Rails:
1. Generating JavaScript code
RJS enables you to generate JavaScript code from your Ruby code, making it easier to update specific parts of your web page without a full page refresh. This is particularly useful for creating AJAX-based features like form submissions, button clicks, and content updates.
2. Simplifying AJAX development
By using RJS, you can write your AJAX logic in Ruby instead of JavaScript. This can make the development process more efficient, especially for developers who are more comfortable with Ruby than JavaScript.
