Fastest way to list children

I want to see which one is more efficient

check what is faster

Conclusion: If your array length is small (less than 200) use Math, otherwise for large dataset "For loop" is faster.

Test String.match with regex against String.split with string. We are splitting a string at the spaces.

how much of a performance deficit you can expect from using Array.includes instead of manually writing a chain of logical ORs
