 ## ![✔] 7.1. Prefer native JS methods over user-land utils like Lodash
 
  **TL;DR:** It's often more penalising to use utility libraries like `lodash` and `underscore` over native methods as it leads to unneeded dependencies and slower performance.
- Bar in mind that with the introduction of the new V8 engine alongside the new ES standards, native methods were improved in such a way that it's now about 50% more performant than utility libraries.

 **Otherwise:** You'll have to maintain less performant projects where you could have simply used what was **already** available or dealt with a few more lines in exchange of a few more files.

-### Code Example – Benchmark test on `_.concat`/`Array.concat`
+### Example: benchmark comparison - Lodash vs V8 (Native)
+The graph below shows the mean of the benchmarks for a variety of Lodash methods, this shows that Lodash methods take on average 146.23% more time to complete the same tasks as V8 methods.

 const _ = require('lodash'),

   Suite = require('benchmark').Suite,
-  chalk = require('chalk');
-
-function onComplete() {
-  let fastest = String(this.filter('fastest').map('name')),

-    [4]
-  ]))
-  .add('underscore', () => __.concat(a0, 2, [3], [
-    [4]
-  ]))
-  .add('native', () => a0.concat(2, [3], [
-    [4]

 Which returns this:
-```bash
-lodash x 1,896,368 ops/sec ±5.64% (89 runs sampled)
-underscore:
-native x 2,488,685 ops/sec ±6.46% (86 runs sampled)
-	Benchmark: concat
-The fastest is native
-The slowest is lodash
