`Array.prototype.reverse` reverses the elements of an array in place, meaning the original array is modified. It returns the reference to the same array with elements in reverse order. 

const arr = [1, 2, 3];
arr.reverse();
console.log(arr); // [3, 2, 1]

The NOT function reverses the logical value of its argument. For example, =NOT(A1>10) returns TRUE if A1 is not greater than 10, and FALSE if A1 is greater than 10. This function is useful for negating conditions in logical tests.
