Have you ever heard of immutability in JavaScript? If not, don’t worry — it’s a concept that is becoming increasingly popular among developers as they discover its benefits for improving code quality, reducing bugs, and enhancing performance. This guide will introduce you to immutable operations in JavaScript and show you some practical ways to use them in your own projects.
What are Immutable Operations?
In programming, an object or data structure is said to be immutable if its state cannot be changed after it has been created. Instead, when we want to change an immutable object, we create a new copy of it with the desired changes.
This might sound like an unnecessary extra step, but there are many good reasons why using immutable objects can make our code better. For one thing, it makes it easier to reason about what is happening in our program, since we know that once an object has been created, it won’t suddenly change out from under us.
It also helps prevent accidental modifications, making it less likely that we will introduce bugs into our code. Additionally, because immutable…
