arr-reduce

Fast array reduce that also loops over sparse elements.

npm i arr-reduce --save

Callback params

The callback is executed on every element in the supplied array:

prev: this is the "accumulator". This value is either the result of the last callback invocation, or the initial value if specified.
curr: the current array element being looped over
i: the index of the current element
arr: the array that is being looped over.

Examples

var reduce = require('arr-reduce');

reduce([1, 2, 3, 4, 5], function (prev, curr) {
  return prev + curr;
});
//=> '15'

Pass an initial value:

reduce(['b', 'c'], function (prev, curr) {
  return prev.concat(curr);
}, ['a']);

//=> ['a', 'b', 'c']

Install dev dependencies:

npm i -d && npm
