JavaScript switch case multiple conditions | Example code

  • by

You can use multiple conditions in the switch case same as using in JavaScript if statement.

switch (true) {
  case a && b:
    // do smth
  case a && !b:
    // do other thing

You can do that but the switch statement will switch on the result of the expression you provide.

Given you have a logical and (&&) in your expression there are two possible outcomes defined on how && works.

  1. if the left hand expression evaluates to true the expression will be equal to the evaluation of the second part.
  2. if the left hand expression evaluates to false the whole expression will evaluate to false.
