Too Long; Didn't Read
ECMAScript 5 introduced array methods like isArray, forEach, map, filter, every, some. But let’s talk about my favorite one: the awesomereduce method. It executes a callback function (provided by the user) on each element of the array, resulting in a single output value. The return value is assigned to the accumulator, whose value is remembered across each iteration throughout the array and ultimately becomes the final, single resulting value. It allows you to take an array and reduce its values to basically anything that can be derived from data it holds.
