Benchmark: Word split - MeasureThat.net

Script Preparation code:

function splitWords(text) {
    let word = '', newText = '';
    const capReg = new RegExp(/^[A-Z]$/);
    const alphaNumReg = new RegExp(/^[a-z0-9]$/);

    for (let i = 0; i <= text.length - 1; i++) {
        if (
            capReg.test(text[i]) && capReg.test(text[i + 1]) && alphaNumReg.test(text[i + 2]) ||
            alphaNumReg.test(text[i]) && capReg.test(text[i + 1]) ||
            !text[i + 1]
        ) {
            newText = `${newText} ${word}${text[i]}`;
            word = '';
        } else {
            word = word + text[i];
        }
    }

    return newText;
}
