Benchmark: Split vs RegEx Brackets

Script Preparation code:

function generateSamples(size) {
    const random = (min, max) => Math.floor(Math.random() * (max -min + 1) + min);
	const samples = [];
    for(let i = 0; i < size; i++) {
  		const type = random(1, 200);
  		const index = random(1, 200);
    	samples.push("T_" + type + "["+ index + "]");
    }
    return samples;
}
var samples = generateSamples(20000);

Tests:

Split
var values = samples.map(x => x.split("[")[0]);
RegEx
var values = samples.map(x => x.match(/T_\d+/)[0]);
