Node.js 18 has been released, bringing lots of exciting new features for developers. With every release, Node.js continues to evolve, enabling developers to create faster and more efficient applications.
In this article, we’ll take a closer look at some of the features in Node.js 18, along with examples of how to use them.

Speed and Memory

Node.js 18 comes with the latest version of the V8 engine, version 10.1. This version includes several performance optimizations that improve the speed and memory efficiency of JavaScript code. One of the new features is inline caching, which reduces the time taken to look up properties and functions in JavaScript objects.

We will take the sample code, and run it on nodeJS 18 and its previous version and observe the difference.

const user = { name: "abhinav", age: 28, city: "berlin" };
console.time('lookup');
for (let i = 0; i < 1000000; i++) {
  const name = user.name;
}
console.timeEnd('lookup');

Here is the result of version 16.19.1
