Constants, Object.freeze, Object.seal and Immutable in JavaScript
Introduction In this article, we're diving into Immutable and Mutable in JavaScript, while also exploring how functions like Object.freeze() and Object.seal() relate to Immutable . This is a pretty important topic that can be super helpful in projects with complex codebase. So, what's Immutable? Immutable is like a property of data in JavaScript. It means once the data is created, it can't be changed. This allows for better memory management and catching changes promptly. This is a big deal and totally contrasts with Mutable, which is the default nature when you initialize data in JavaScript. Implementing Immutable in a project makes development much smoother, reduces issues that crop up, and saves a ton of effort and time for maintenance down the road. But what happens if you don't use Immutable? Let me give you an example of how changing data during development can lead to some serious issues. let info = { name: "name" , address: "addres...
