eslint-plugin-neat-ternaries

format chained ternaries to optimize readability

• Each line correspond to a case (condition/value pair)
• The chained ternary is formatted in two columns:
  • The left column is for conditions
  • The right column is for the matching values (including the default value)

Like this:

const neatTernary = someCondition       ? someValue :
                    someOtherCondition  ? someOtherValue :
                    yetAnotherCondition ? yetAnotherValue :
                                          defaultValue
