find-index

An implementation of the ES6 method Array.prototype.findIndex as a standalone module and a ponyfill.

Finds an item in an array matching a predicate function, and returns its index.

Fast both when thisArg is used and also when it isn't.

usage

npm install find-index
var findIndex = require('find-index/findIndex')
var findIndex = require('find-index/ponyfill') // will use native Array#findIndex if available.
var findLastIndex = require('find-index/findLastIndex') // search backwards from end
findIndex(array, callback[, thisArg])
findLastIndex(array, callback[, thisArg])
Parameters:
  array
    The array to operate on.
  callback
    Function to execute on each value in the array, taking three arguments:
      element
        The current element being processed in the array.
      index
        The index of the current element being processed in the array.
      array
        The array findIndex was called upon.
  thisArg
    Object to use as this when executing callback.

Based on array-findindex
