Benchmark: indexOf vs includes in strings

Script Preparation code:

var long = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.';
var short = 'file.ext';

var s1 = 'tempor';
var s2 = '.ext';

var re1 = /tempor/;
var re2 = /\.ext/;

Tests:

includes
long.includes(s1); long.includes(s2); short.includes(s1); short.includes(s2);
!~indexOf
!~long.indexOf(s1); !~long.indexOf(s2); !~short.indexOf(s1); !~short.indexOf(s2);
indexOf > -1
long.indexOf(s1) > -1; long.indexOf(s2) > -1; short.indexOf(s1) > -1; short.indexOf(s2) > -1;
indexOf !== -1
long.indexOf(s1) !== -1; long.indexOf(s2) !== -1; short.indexOf(s1) !== -1; short.indexOf(s2) !== -1;
test
re1.test(long); re2.test(long); re1.test(short); re2.test(short);
match
long.match(re1) !== null; long.match(re2) !== null; short.match(re1) !== null; short.match(re2) !== null;
