Benchmark: indexOf vs search 3

Script Preparation code:

var NEWLINE = /\x0d\x0a|[\x0a\x0d\u2028\u2029]/;
var NEWLINE_U = /\x0d\x0a|[\x0a\x0d\u2028\u2029]/u;
var str = 'foobarbaz!'.repeat(1000);
window.result = 0;

Tests:

indexOf
result += str.indexOf('\n');
search
result += str.search(NEWLINE);
search (u)
result += str.search(NEWLINE_U);
exec
const match = NEWLINE.exec(str); if (match) result += match.index;
exec (U)
const match = NEWLINE_U.exec(str); if (match) result += match.index;
indexOf all
let index = str.indexOf('\n'); if (index === -1) index = str.indexOf('\r'); if (index === -1) index = str.indexOf('\u2028'); if (index === -1) index = str.indexOf('\u2029'); result += index;
