The following is (in my book) an elegant approach to avoid nested ternary operations. In response to this article: https://medium.com/chrisburgin/rewriting-javascript-replacing-the-switch-statement-cfff707cf045

ternary.js

const name = 'Martin'
const customer = false
const human = true

// The object’s keys are irrelevant, since `Object.values` just spits out the object properties into an array.
const ternaryOps = Object.values({
  1: name === 'Joe' ? 'Hi Joe!' : null,
  2: customer ? 'Dear customer,' : null,
  3: human ? `Hey ${name}!` : null,
  default: 'To Whom It May Concern,'
})
// Find the first property that has passed the test
.find(x => x)

console.log(ternaryOps) // Spits out “Hey Martin!”
