Difference between sort() and toSorted()

In javascript, both method do the same job, except original array mutation.

sort() method mutate the original array. No need to store the return value in variable.

var arr = [1,2,1000];
arr.sort();
console.log(arr);
// console.log() => 1, 1000, 2

toSorted() method does not mutate the original array. Need to store the return value in variable.

var arr = [1,2,1000];
var sortedArr = arr.toSorted();
console.log(sortedArr);
// console.log() => 1, 1000, 2

One thing to add about the both function:
sort() is way more perf than toSorted()

@pedrobruneli Yes, 100% Agree.
Reason behind the performance and memory usage, sort() does not create the new Array while perform the operation. but toSorted() create the new Array to perform the operation.
