string in JavaScript are immutable, but when we use 'let' with strings , it becomes changeable, which tends to mean that they are mutable, how can we justify that strings are immutable yet it is mutable when use with let?

You're changing the variable, not the string.Bergi– Bergi2023-07-14 16:50:26 +00:00Commented Jul 14, 2023 at 16:50

Let me help you with that using an example.
Consider we declare a string using let
let someString = 'This is a String'
now you can Re-assign that variable someString to a new value which means let variables can be reassigned.
someString = 'Some new Value'
But Strings are immutable in the sense that you can't mutate the content of the String.
someString[1] = 'A' //This is Invalid since Strings are Immuatable
Happy Coding :)
