How Can I Reverse An Array In Javascript Without Using Libraries

Reversing an array can be a useful skill to have in your coding toolkit, especially when working with JavaScript. While there are libraries and built-in functions that can help you achieve this, sometimes you may want to reverse an array without relying on external dependencies.

Let's dive into how you can reverse an array in JavaScript without using libraries. One approach to reverse an array is to loop through the array and swap the elements. Here’s how you can do it:

function reverseArray(arr) {
  let start = 0;
  let end = arr.length - 1;

  while (start  {
    return [element, ...reversed];
  }, []);
}

// Example usage
const originalArray = [1, 2, 3, 4, 5];
const reversedArray = reverseArray(originalArray);
console.log(reversedArray); // Output: [5, 4, 3, 2, 1]

In this implementation, the `reduce` method iterates over the elements of the original array, building a new array by prepending each element to the `reversed` array.

Both of these methods provide simple and efficient ways to reverse an array in JavaScript without relying on external libraries. It's important to understand the logic behind these solutions so that you can adapt and modify them as needed in your projects.

By mastering these techniques, you can reverse arrays in JavaScript with confidence and add a valuable skill to your programming repertoire. Experiment with these methods, apply them to your projects, and keep exploring new ways to manipulate arrays in JavaScript. Happy coding!
