_switch

The _switch operator evaluates an array of conditions and returns the then argument of the first item for which the if argument evaluates to true. If no condition evaluates to true, the value of the default argument is returned.

Arguments

object

• branches: if: boolean: The boolean result of a test. then: any: The value to return if the test is true.
• default: any: The value to return if all the if tests are false.

Examples

Return a value based on a series of conditions:

_switch:
  branches:
    - if:
        _eq:
          - x
          - y
      then: A
    - if:
        _eq:
          - x
          - z
      then: B
  default: C

Returns: "C" since both of the if tests are false.
