Module "public/strike"

Const strike

• strike<TIn, TOut>(val: TIn, ...matchers: Array<AnyExecutor<TIn, TOut>>): TIn | TOut

• description

  Use this function when you have a value and you want to test it against a pattern.

  strike will iterate through your Matchers and use the first match's Transformer to map val to a TOut.

  strike is comparable to the match operator in Rust, F#, and other languages with idiomatic Pattern Matching.
