What are some examples of immutable types in JavaScript?
In JavaScript, examples of immutable types include strings, numbers, and booleans. They cannot be changed after creation.
Can you explain why strings are considered immutable?
Strings are immutable because any operation that seems to modify a string actually creates a new string instead of changing the original.
What about arrays? Are they immutable?
No, arrays in JavaScript are mutable. You can change their elements, add or remove items without creating a new array.
Are there any ways to create immutable data structures in JavaScript?
Yes, you can use libraries like Immutable.js or leverage ES6 features like Object.freeze() to create immutable objects.
