splice()

The splice() method adds and/or removes array elements.
The splice() method overwrites the original array.

slice()

The slice() method returns a shallow copy of a portion of an array into a new array object selected from begin to end (end not included). The original array will not be modified.
The slice() method does not alter the original array, and both arrays will have the same behavior after any change to one is applied to the other.

sort()

The sort() method sorts the elements of an array in place and returns the sorted array.
The sort() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

reverse()

he reverse() method reverses an array in place. The first array element becomes the last and the last becomes the first.
The reverse() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

Join()

The join() method joins the elements of an array into a string.
The join() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

pop()

The pop() method removes the last element from an array and returns that element.
The pop() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

push()

The push() method adds one or more elements to the end of an array and returns the new length of the array.
The push() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

shift()

The shift() method removes the first element from an array and returns that element.
The shift() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

unshift()

The unshift() method adds one or more elements to the front of an array and returns the new length of the array.
The unshift() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

entries()

The entries() method returns a new Array Iterator object that contains the key/value pairs for each index in the array.
The entries() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

concat()

The concat() method is used to join two or more arrays, and returns a copy of the joined arrays.
The concat() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

filter()

The filter() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

indexOf()

The indexOf() method returns the first index at which a given element can be found in the array, or -1 if it is not present.
The indexOf() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

lastIndexOf()

The lastIndexOf() method returns the last index at which a given element can be found in the array, or -1 if it is not present.
The lastIndexOf() method does not change the original array, and both arrays will have the same behavior after any change to one is applied to the other.

charAt()

charAt() method returns the character at the specified index.

concat()
