Implementation of "RGBToHex" in typescript, javascript and deno.

TS JS Deno

Converts the values of RGB components to a color code.

Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (<<) and toString(16), then String.padStart(6,'0') to get a 6-digit hexadecimal value.

const RGBToHex = (r: number, g: number, b: number, hash: "#" | "" = "") =>
  hash + ((r << 16) + (g << 8) + b).toString(16).padStart(6, "0");
RGBToHex(255, 165, 1); // 'ffa501'
RGBToHex(255, 165, 1, "#"); // '#ffa501'
