Benchmark: regex vs compiled regex vs includes

Script Preparation code:

// Note that var is used to take advantage of global scope
var text = `{"A lot more stuff than what we have before and by a lot more i don't actually mean that much more but it's still more FetchInputEventCrashTimeout":"Watchdog FetchInputEvent were not being fed for 30000 milliseconds.Crash timeout was set to 30000 milliseconds."}`
var regex = new RegExp('\bWatchdog');
var regexVar = /\bWatchdog/;

Tests:

includes
const result = text.includes("Watchdog"); if (result){ console.log("something"); }
regex
const result = text.match(/\bWatchdog/); if (result){ console.log("something"); }
compiled regex
// Note, the following is included in the preperation code // var regex = new RegExp('\bWatchdog'); const result = regex.test(text) if (result){ console.log("something"); }
variable regex
const result = regexVar.test(text) if (result){ console.log("something"); }
