array-reduce-sum
Package for summing numbers in an array.
- Returns sum of numbers in an array.
- Takes an optional second argument for initial value
Behavior similar to Array.prototype.reduce() accumulator pattern that takes value inputs in an array from left-to-right and reduces to a single value.
var sum = [0, 1, 2, 3].reduce(function(acc, val) { return acc + val;}, 0);// sum is 6 Installation
npm install array-reduce-sum --saveSyntax
var fn = require('array-reduce-sum');fn(array, [initialValue]); // initialValue optional // initialValue should be a number not a stringUsage
var sumArray = require('array-reduce-sum'); sumArray([5]);// => 5 sumArray([5,10]);// => 15 // Coerces numbers as strings to behave like numberssumArray(["5", "10"]);// => 15 // Optional second argument with initial valuesumArray([5,10], 20);// => 35Support
