1. Exploit Destructuring for Multiple Returns

Destructuring is a nifty tool to unpack values from arrays or properties from objects into distinct variables. But did you know you can also use destructuring to effectively return multiple values from a function?

function getRaccoonStats() {
  const name = "Rascal"
  const weight = "15 lbs"
  const age = "3 years"

  return { name, weight, age }
}

const { name, weight, age } = getRaccoonStats()
console.log(`Meet ${name}, a ${weight}, ${age} old raccoon 🦝.`)
