Benchmark: .includes() vs .test() vs .match() vs .indexOf() (w/ -1 != and !==)

Script Preparation code:

var url='https://www.google.com/matchthis/other/args'

Tests:

text.includes()
url.includes('matchthis')
regex.test()
/matchthis/.test(url)
string.match()
url.match(/matchthis/)
string.indexOf()
url.indexOf('matchthis') >= 0
string.indexOf() !== -1
url.indexOf('matchthis') !== -1
string.indexOf() != -1
url.indexOf('matchthis') != -1
