Is it really faster than `String.indexOf()`?

[subzero10]

Hello, nice work!

I tried your benchmark with different sets of inputs, a combination of short, medium and long text or search pattern, i.e.:

• short text, short search pattern,
• short text, short search pattern,
• short text, long search pattern,
• medium text, short search pattern,
• etc.

My results show that String.indexOf() is faster than this implementation. I read somewhere that the implementation of indexOf in Javascript implements the Boyer-Moore algorithm along with some tweaks based on the inputs.

I think that your test cases in the benchmark are not general enough. You are building a large string with a repeated set of characters. I generated random strings using the crypto module.

Please note that I am not criticizing your work in any way, I just wanted to share my findings after going through your code.

Thanks!
