It might make sense to add a third argument to that method, so that it works
roughly like this:
Array.prototype.find = function (predicate, returnValue = undefined,
thisArg = undefined) {
var arr = Object(this);
if (typeof predicate !== 'function') {
throw new TypeError();
}
for(var i=0; i < arr.length; i++) {
if (i in arr) { // skip holes
var elem = arr[i];
if (predicate.call(thisValue, elem, i, arr)) {
return elem;
}
}
}
return returnValue;
}
