Hexadecimal color to RGB color JavaScript

We are required to write a JavaScript function that takes in a hexadecimal color and returns its RGB representation.

The function should return an object containing the respective values of red green and blue color −

For example:

hexToRgb('#0080C0') should return 0, 128, 192

The code for this will be −

const hex = '#0080C0';
const hexToRGB = hex => {
   let r = 0, g = 0, b = 0;
   // handling 3 digit hex
   if(hex.length == 4){
      r = "0x" + hex[1] + hex[1];
      g = "0x" + hex[2] + hex[2];
      b = "0x" + hex[3] + hex[3];
      // handling 6 digit hex
   }else if (hex.length == 7){

      r = "0x" + hex[1] + hex[2];
      g = "0x" + hex[3] + hex[4];
      b = "0x" + hex[5] + hex[6];
   };

   return{
      red: +r,
      green: +g,
      blue: +b
   };
}
console.log(hexToRGB(hex));

Following is the output on console −

{ red: 0, green: 128, blue: 192 }
