// bad
const foo = (bar, baz) => {
  return foo + bar
}
const foo = (bar, baz) => {
  return { bar, baz }
}

Function Chains

Function chains longer than 3 should be broken onto new lines

// good
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .value()
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .map(transformFoosAgain)
  .value()

// bad
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .map(transformFoosAgain)
  .value()
