The reduce () method applies a function against an accumulator and each value of the array (from left-to-right) to reduce it to a single value. (Emphasis mine) So you see, although you can manipulate reduce to return a new array, it's general usage is to reduce an array to a single value.
57 I have this code for a class where I'm supposed to use the reduce() method to find the min and max values in an array. However, we are required to use only a single call to reduce. The return array should be of size 2, but I know that the reduce() method always returns an array of size 1.
You can use reduce method as bellow; If you change the 0 (zero) to 1 or other numbers, it will add it to total number. For example, this example gives the total number as 31 however if we change 0 to 1, total number will be 32.
