Benchmark: Repeated use of includes vs match

Script Preparation code:

var target = 'Very Long Target String';
const part = 'this is 12345 part of Target long string String that will not match';
const parts = Array(50).fill(part);
const targetPart = `this is a string that might or might not have our ${target} embedded in it`;
const nonTargetPart = 'and this is a string that does not really have have anything much interesting in it';
parts.push(targetPart);
const longTarget = parts.join(' ');
parts.pop();
parts.push(nonTargetPart);
const longNonTarget = parts.join(' ');

var stringList = [];
for (let i = 0; i < 10000; i++) {
    stringList.push(longTarget);
    stringList.push(longNonTarget);
}
var targetRe = new RegExp(target);

Tests:

Includes
let result = stringList.filter(s => s.includes(target));
Test
let result = stringList.filter(s => targetRe.test(s));
Match
let result = stringList.filter(s => s.match(targetRe));

Amortize the cost of creating a regex across 20,000 applications. Scan a long string. On chrome you only see a difference once the target string is over 15 chars or so. String.includes is best, followed by RegExp.test, then String.match.
