Benchmark: occurrence methods speed

Tests:

regex
const escapedText = '\ P'.replace(/[.|*|+|?|^|$|{|}|(|)|[|]|\||\\]/g, '\\$&'); const searchRegex = new RegExp(escapedText, 'gi'); const count = ('\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P'.match(searchRegex)).length;
split
const count = ('\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P'.split('\ P')).length;
loop
const string = '\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P\ P'; const searchFor = '\ P'; let count = 0; let pos = string.indexOf(searchFor); while (pos > -1) { ++count; pos = string.indexOf(searchFor, ++pos); }
