Which JavaScript Array functions are mutating?


You can also use .concat(), before using your mutation method, to ensure you are not mutating your arrays, eg

const dontMutateMe = [4,5,1,2,3];const sortArray = dontMutateMe.concat().sort(...)


I found this website called Doesitmutate

Have the list of all functions - and tells whether it mutates or not.
