could you add comments next to each statement please? I would need to convert a string to an RGB color. Is this function right for me?

function rgbToHex(r, g, b) {
return "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1);
}
function hexToRgb(hex) {
var result = /^#?([a-f\d]{2})([a-f\d]{2})([a-f\d]{2})$/i.exec(hex);
if(result){
var r= parseInt(result[1], 16);
var g= parseInt(result[2], 16);
var b= parseInt(result[3], 16);
return r+","+g+","+b;//return 23,14,45 -> reformat if needed
}
return null;
}
console.log(rgbToHex(10, 54, 120)); //#0a3678
console.log(hexToRgb("#0a3678"));//"10,54,120"

//returns [23, 14, 45] -> reformat if needed
}
console.log(rgbToHex(10, 54, 120)); // #0a3678
console.log(hexToRgb("#0a3678")); // [10, 54, 120]
