This is need to be able to move to flat config which I am handling in a separate CL. The overrides are there as these packages got update today, so we need to way, but they were last touched 3 years ago, so reviewing their changes upstream as well. Bug: none Change-Id: I61534f881fd4e747c716b42b773f8f7f3e9bc761 Reviewed-on: https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/6063618 Commit-Queue: Nikolay Vitkov <nvitkov@chromium.org> Reviewed-by: Danil Somsikov <dsv@chromium.org>
object.groupby 
An ESnext spec-compliant Object.groupBy shim/polyfill/replacement that works as far down as ES3.
This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the proposed spec.
Getting started
npm install --save object.groupby
Usage/Examples
var groupBy = require('object.groupby');
var assert = require('assert');
var arr = [0, 1, 2, 3, 4, 5];
var parity = function (x) { return x % 2 === 0 ? 'even' : 'odd'; };
var results = groupBy(arr, function (x, i) {
assert.equal(x, arr[i]);
return parity(x);
});
assert.deepEqual(results, {
__proto__: null,
even: [0, 2, 4],
odd: [1, 3, 5],
});
var groupBy = require('object.groupby');
var assert = require('assert');
/* when Object.groupBy is not present */
delete Object.groupBy;
var shimmed = groupBy.shim();
assert.equal(shimmed, groupBy.getPolyfill());
assert.deepEqual(Object.groupBy(arr, parity), groupBy(arr, parity));
var groupBy = require('object.groupby');
var assert = require('assert');
/* when Array#group is present */
var shimmed = groupBy.shim();
assert.equal(shimmed, Object.groupBy);
assert.deepEqual(Object.groupBy(arr, parity), groupBy(arr, parity));
