Embracing Array Immutability with Copy Changes
A New Chapter in JavaScript. 2023
JavaScript, a language that has continuously evolved since its inception, is once again ready to surprise us. This time, it brings a new proposal in the realm of array manipulation methods, which is known as “Change Array by Copy”:
This proposal, put forth by Ashley Claymore and Robin Ricard, aims to revolutionize the way we deal with arrays by advocating for immutability.
Immutability, an essential aspect of functional programming, reduces bugs and complications arising from shared state and mutable data. Embracing immutability helps programmers write safer and more predictable code. This is where the Change Array by Copy proposal steps in.
Unleashing the Power of “Change Array by Copy”
JavaScript’s existing array manipulation methods like reverse(), sort(), and splice() mutate the array in place. Though useful in many scenarios, these methods can lead to unexpected side effects when dealing with shared state…
