Use built-in Array.isArray for isArray

[gquittet]

Description

The isArray is already implemented in JavaScript / Node.js.

I think we should use the Array.isArray function

And Array.isArray is slightly speedier than the custom one written in radash.

Thanks for the PR @gquittet 🙏 I'm going to merge it and publish it in v11.0.0

Would you be willing to share the code/project/setup you used to do the perf tests? I've been thinking of adding a suite to ensure changes don't cause performance regressions but I have little (no) exp with it.

Hello @rayepps 👋

I'm using benchmarkify
but unfortunately it's not maintained anymore since 2 years.

I can look for a solid and maintained solution that is compatible with GitHub Actions.
I'm also developing a NodeJS library so, I'm interested with this aspect of performance analysis using CI.

I keep you in touch when I find a great solution.
