Please don't change Array.prototype, it may interfere with other libraries.

1. This is generally a bad practice.
2. After an hour of debugging my app, I found the cause is in dav :angry:

Example:

$ npm i phone dav
$ node
> var phone = require('phone')
undefined
> phone('+79167045979')
[ '+79167045979', 'RUS' ]
> var dav = require('dav')
undefined
> phone('+79167045979')
SyntaxError: Invalid regular expression: /^7function (predicate) {
    if (this == null) {
      throw new TypeError('Array.prototype.find called on null or undefined');
    }
    if (typeof predicate !== 'function') {
      throw new TypeError('predicate must be a function');
    }
    var list = Object(this);
    var length = list.length >>> 0;
    var thisArg = arguments[1];
    var value;

    for (var i = 0; i < length; i++) {
      value = list[i];
      if (predicate.call(thisArg, value, i, list)) {
        return value;
      }
    }
    return undefined;

This is a common issue, but we can still polyfill by not assigning to the prototype directly but creating a non-enumerable property on it using Object.defineProperty.
