Answer 1

Another tip - if using the implied return shorthand, i.e.:

foo => foo.bar

you are able to write the return expression as multi-line. The only catch is you must include () around the expression. This happens often in React, for example, to improve JSX readability

const myButton = props => (
  
    My Button text!
  
)
