Nodejs (not web):

const rgb = (...args) => 
  Buffer.from(args).toString('hex') // .toUpperCase() // if you are wasteful xD

Not necessarily actually efficient, but definitely hilarious.

General JS:

const rgb = (...args) =>
  args.reduce((a, x, i) => a + x * 0x100 ** (2 /*or args.length*/ - i), 0)
  .toString(16).toUpperCase().padStart(6, '0')
