Can you explain the difference between mutable and immutable state in JavaScript?

Can you give me an example of mutable state?
Absolutely! An array in JavaScript is mutable. You can change its elements or length after it's created.
And what about an example of immutable state?
A common example of immutable state is a string in JavaScript. Once a string is created, it cannot be changed.
