The reduceRight method reduces the array from the last element and keeps only those items that return a value of true from the callback function. This method is used to transform an array into a single value, and it works from right to left. The every method checks whether all of the elements in an array pass the test. The map method creates a new array with the results of calling a provided function on every element in the calling array. The findIndex method returns the index of the first element in an array that satisfies the provided testing function.
