Thereduce()method works from left-to-right in the array. See alsoreduceRight(). Thereduce()method does not reduce the original array. This example finds the sum of all numbers in an array: Example constnumbers = [45,4,9,16,25]; ...
functiongetSum(total, num) { returntotal - num; } Try it Yourself » Description ThereduceRight()method executes a reducer function for each array element. ThereduceRight()method works from right to left. ThereduceRight()method returns a single value: the function's accumulated result. ...
Invoking this method is equivalent to creating an array as follows: <blockquote> text/java Copy int[] x = {length}; Array.newInstance(componentType, x); </blockquote> The number of dimensions of the new array must not exceed 255. Java documentation for java.lang.reflect.Array....
