match

Selects the output for which the label value matches the input value, or the fallback value if no match is found. The input can be any expression (for example, ["get", "building_type"]). Each label must be unique, and must be either:

• a single literal value; or

• an array of literal values, the values of which must be all strings or all numbers (for example [100, 101] or ["c", "b"]).

The input matches if any of the values in the array matches using strict equality, similar to the "in" operator. If the input type does not match the type of the labels, the result will be the fallback value.
