JavaScript Beautifier

JavaScript Beautifiers and JavaScript Viewers are essential tools for working with JavaScript code, especially when it comes to improving readability or viewing complex, compressed scripts.

1. JavaScript Beautifier
A JavaScript Beautifier is used to take minified or compressed JavaScript code and format it into a more readable and structured format. It adds proper indentation, line breaks, and spacing, making the code easier to read, debug, and maintain.

Features:
Indentation: Adds proper indentation to nested blocks (loops, conditionals, functions).
Line Breaks: Adds line breaks for clarity, making the code easier to follow.
Comments: In some cases, it can preserve comments to help with code documentation.
Code Highlighting: Some beautifiers may provide color coding or syntax highlighting to make the code more visually appealing.

2. JavaScript Viewer
A JavaScript Viewer is a tool that allows you to inspect and view the structure of your JavaScript code, typically showing it in a more readable format. It's especially useful when you have minified JavaScript and want to see the structure of the code or its execution flow.

Features:
Tree View: Displays the JavaScript functions and variables in a hierarchical tree-like structure.
Code Visualization: Shows how the code interacts with objects, functions, and other variables.
Live Preview: Some viewers allow you to see live outputs of JavaScript code execution in real-time.

Use Cases for JavaScript Beautifiers and Viewers:
Beautifier:

Improving Readability: When you receive minified JavaScript or work with complex code, beautifying it can make it easier to understand.
Code Maintenance: Beautified code is easier to maintain and debug, especially in collaborative environments.
Debugging: Helps to quickly pinpoint issues by making the code structure clear and organized.
Viewer:

Understanding Code Structure: When dealing with large or complex JavaScript files, a viewer allows you to quickly visualize the hierarchy of functions, variables, and execution flow.
Live Testing: Viewers often provide tools for running the JavaScript code and seeing the output instantly, which is valuable for testing and experimenting.
