Unminify JavaScript

If you have ever worked with JavaScript, you may have come across a minified version of the code. Minification is a process of removing any unnecessary characters from the code to make it smaller in size. This is usually done to improve the load time of a webpage or application. However, it can be challenging to read and understand minified code, especially for beginners or those unfamiliar with the specific codebase. In such cases, it may be necessary to unminify the code to make it more readable.

Method 1: Online Tools

One way to unminify JavaScript is to use online tools. There are many free online tools available that can help you with this. One such tool is Unminify.com. To unminify your code using this tool, follow these steps:

  1. Copy the minified code that you want to unminify.
  2. Go to Unminify.com.
  3. Paste the code into the text area provided on the website.
  4. Click on the "Unminify" button.
  5. The unminified code will be displayed on the page.

You can copy and use this unminified code as needed.

Method 2: Code Editor Plugins

If you work with JavaScript regularly, you may want to consider using a code editor plugin to unminify your code. Many popular code editors like Visual Studio Code, Atom, and Sublime Text have plugins available that can help you unminify your code with just a few clicks.

For example, if you use Visual Studio Code, you can install the Beautify plugin to unminify your code. Once the plugin is installed, you can simply select the minified code in your editor and click on the "Beautify" button in the toolbar or use the keyboard shortcut. The plugin will unminify the code and make it more readable.

Method 3: Manual Unminification

If you don't want to use online tools or code editor plugins, you can also unminify JavaScript manually. This can be a time-consuming process, but it can give you more control over the unminification process.

To unminify JavaScript manually, follow these steps:

  1. Copy the minified code into a text editor.
  2. Replace all semicolons (;) with semicolons followed by a line break (;
    ).
  3. Replace all comma separators (,) with commas followed by a line break (,
    ).
  4. Replace all opening curly brackets ({) with opening curly brackets followed by a line break ({
    ).
  5. Replace all closing curly brackets (}) with a line break followed by closing curly brackets (}
    ).

Once you have made these changes, the code will be more readable and easier to understand.


// Minified Code
function hello(){return"Hello World!"}function add(a,b){return a+b}console.log(hello()),console.log(add(2,3));

// Unminified Code
function hello() {
  return "Hello World!"
}

function add(a, b) {
  return a + b
}

console.log(hello());
console.log(add(2, 3));
