Function decide

decide<TToken, TOptions, TValue>(p: Parser<TToken, TOptions, Parser<TToken, TOptions, TValue>>): Parser<TToken, TOptions, TValue>
Make a parser that runs a given parser and then a dynamically returned parser.

A nonmatch is returned if any of two parsers did not match.

Compared to condition this can have any complex logic inside.

chain allows to reuse the first parser.
Type Parameters
- TToken
- TOptions
- TValue
Parameters
- p: Parser<TToken, TOptions, Parser<TToken, TOptions, TValue>>
  
  A parser that returns another parser as a value. If it consumes the input then the returned parser will be called with the new position.
Returns Parser<TToken, TOptions, TValue>
