default function:

  • Can also be called as defaults

  • Can also be called as or_else

Get the first non empty value.

Examples:

  • running: (default (get . 1), (get . "key-1"), 22) for input: {"key-1": 1, "key-2": false} will give: 1 Because the first get will return nothing because the input is an object and get should have a string argument, the second get will return 1, which is not a nothing, so it will be the returned value.
  • running: (default (get . 1), (get . "key-3"), 22) for input: {"key-1": 1, "key-2": false} will give: 22 Because all the get will return nothing, so 22 is the first non nothing argument.
  • running: (default (.get 1), (.get 2)) for input: 100 will return nothing
