About JavaScript Beautifier

What is JavaScript Beautifier?

JavaScript Beautifier is a powerful tool that formats and prettifies your JavaScript code, making it more readable and maintainable. By applying consistent indentation, spacing, and formatting rules, your code becomes easier to understand, debug, and collaborate on.

This tool is essential for web developers looking to improve code quality, enhance team collaboration, and streamline the development process.

Why Beautify JavaScript?

  • Improved Readability:Well-formatted code is easier to read and understand.
  • Easier Debugging:Proper indentation and formatting help identify errors quickly.
  • Team Collaboration:Consistent code style across the team reduces friction.
  • Code Maintenance:Clean code is easier to maintain and update over time.
  • Learning Resource:Properly formatted code serves as a better learning tool.

Before Beautification

function factorial(n){if(n===0||n===1){return 1;}else{return n*factorial(n-1);}}function fibonacci(n){if(n<=1){return n;}else{return fibonacci(n-1)+fibonacci(n-2);}}function sumArray(arr){let sum=0;for(let i=0;i

After Beautification

function factorial(n) { if (n === 0 || n === 1) { return 1; } else { return n * factorial(n - 1); } }  function fibonacci(n) { if (n <= 1) { return n; } else { return fibonacci(n - 1) + fibonacci(n - 2); } }  function sumArray(arr) { let sum = 0; for (let i = 0; i < arr.length; i++) { sum += arr[i]; } return sum; }  const person = { name: "John", age: 30, address: { street: "123 Main St", city: "New York", state: "NY", zip: "10001" }, hobbies: ["reading", "running", "swimming"] };  console.log("Factorial of 5:", factorial(5)); console.log("Fibonacci sequence:", fibonacci(6)); console.log("Sum of array:", sumArray([1, 2, 3, 4, 5]));
