Benchmark: Fastest results - MeasureThat.net

Script Preparation code:

window.case1 = new Proxy({}, {
  isNumeric(str) {
    return !isNaN(parseInt(str));
}
});
window.case2 = new Proxy({}, {
 isNumeric(str) {
    for (let i = 0; i < str.length; i++) {
        // check if the character at position i is not a digit
        if (str[i] < '0' || str[i] > '9') {
            return false;
        }
    }
    return str.length > 0;
	}
});
window.case3 = new Proxy({}, {
 isNumeric(str) {
    return /^[0-9]*$/.test(str);
}
});

window.gabage1 = 0;
window.gabage2 = 0;
window.gabage3 =0;

Tests:
