YouTube Excerpt: Watch the entire #JavaScriptJanuary series from the beginning! https://www.youtube.com/playlist?list=PLkwxH9e_vrALlH7D0XLDn2td-uoHqHFxq The JavaScript reduce() method reduces an array to a single value. It executes a provided function for each value in the array and the returned value is stored in an accumulator. The function is not executed for array elements without values and it does not change the original array. First we create a new variable, then we reference the array and add .reduce(). The reduce() method accepts two parameters. The first is a function. The function has access to the accumulator, current value, current index, and the entire original array. The second parameter after the function is an optional initial value for the accumulator. If the initial value is not included, the first element in the array will be used and skipped. I'll be releasing a new video every day in January!
