    foldl CI

    Apply a function to each value in a collection, accumulating the results into a single return value.

    Installation

    $ component install ndhoule/foldl
    $ npm install @ndhoule/foldl

    API

    reduce(iterator : Function, accumulator : *, collection : Array|Object)

    Reduces all the values in a collection down into a single value. Does so by iterating through the collection from left to right, repeatedly calling an iterator function and passing to it four arguments: (accumulator, value, index, collection).

    foldl(function(total, n) {
      return total + n;
    }, 0, [1, 2, 3]);
    //=> 6
    
    var phonebook = { bob: '555-111-2345', tim: '655-222-6789', sheila: '655-333-1298' };
    
    foldl(function(results, phoneNumber) {
     if (phoneNumber[0] === '6') {
       return results.concat(phoneNumber);
     }
     return results;
    }, [], phonebook);
    // => ['655-222-6789', '655-333-1298']
