Immutable data handling is a core concept in modern JavaScript development, aiming to prevent unexpected side effects and bugs by ensuring that data remains unchanged once created. Rest and spread operators are powerful tools that play a key role in facilitating immutable data handling.
In this article, we’ll explore how rest and spread operators can streamline your code and promote immutability, accompanied by practical and up-to-date code examples.
Understanding Immutable Data Handling
Before diving into rest and spread operators, let’s briefly discuss what immutable data handling entails and why it’s important in JavaScript development.
Immutable data refers to data that cannot be changed after it’s created. Instead of modifying existing data, immutable data handling involves creating new data structures whenever changes are needed. This approach helps prevent unintended side effects and makes code easier to reason about and debug.
