Benchmark: how fast is regex3?

Script Preparation code:

const prepared = /[.*+?^${}()|[\]\\]/g;

Tests:

instantiate new regex
const blah = "whatever" const r = blah.replace(/[.*+?^${}()|[\]\\]/g, "\\$&")
use existing regex
const blah = "whatever" const r = blah.replace(prepared, "\\$&")
just make a regex
const newOne = /[.*+?^${}()|[\]\\]/g;
just make a string
const blah = "foo"
