Converts RGB/RGBA string to object

parseRGBString.js

// pass a rgb/rgba string value into this function i.e. rgb(0,0,0)
// and it will return an object of { r: 0, g: 0, b: 0, a: 1 }

const parseRGBString = str => {
  const vals = str.substring(str.indexOf('(') + 1, str.length - 1).split(', ');

    r: parseInt(vals[0], 10),
    g: parseInt(vals[1], 10),
    b: parseInt(vals[2], 10),
    a: parseFloat(vals[3])
  };
