10 JavaScript Tricks You Might Not Be Aware Of 🤞🚀

Greetings, fellow JavaScript enthusiasts! In this session, we’ll explore a collection of advanced JavaScript techniques designed to elevate your coding prowess. Whether you’re an experienced developer or a newcomer, mastering these tricks is bound to take your JavaScript skills to the next level.

10 JavaScript Tricks

1. Destructuring with Renaming

Destructuring assignment is a powerful tool. Were you aware that you can rename variables during assignment?

const { prop1: newName1, prop2: newName2 } = object;

Here, we rename prop1 and prop2 to newName1 and newName2, respectively.

2. Memoization for Improved Performance

Memoization is a technique used to cache function results for better performance. Here’s a simple implementation:

const memoizedFunction = (function () {
  const cache = {};
  return function (args) {
    if (!(args in cache)) {
      cache[args] = computeResult(args);
    }
    return cache[args];
  };
})();

By caching results, we avoid redundant computations.
