arr-reduce

1.0.1 • Public • Published

arr-reduce NPM version Build Status

Fast array reduce that also loops over sparse elements.

Install with npm

npm i arr-reduce --save

Usage

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']

Run tests

Install dev dependencies:

npm i -d && npm
