What's wrong with modern syntax?

Benchmark CI: https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-node-micro-benchmarks/916/ (queued, will 404 until it starts).

Nothing wrong with the syntax, the problem is with array iteration which relies on user-mutables methods:

delete Array.prototype[Symbol.iterator];
const [a, b, c] = [1,2,3];

@aduh95 The benchmark didn't run properly. Here is the new link:

Hope there are no regressions! 🤞

The benchmark stops working after two minutes… I'm not sure if it's a problem with our CI or the benchmark itself.

I'm splitting it into several runs to see if that helps:
https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-node-micro-benchmarks/920/
https://ci.nodejs.org/view/Node.js%20benchmark/job/benchmark-node-micro-benchmarks/921/

No significant perf improvements or regressions.
