Function reduceLeft

reduceLeft<TToken, TOptions, TAcc, TValue>(
    acc: TAcc,
    p: Parser<TToken, TOptions, TValue>,
    reducer: (
        acc: TAcc,
        v: TValue,
        data: Data<TToken, TOptions>,
        i: number,
        j: number,
    ) => TAcc,
): Matcher<TToken, TOptions, TAcc>
Make a Matcher that takes 0 or more matches from the same parser and reduces them into one value in left-to-right (first-to-last) order.

Note: accumulator is the left (first) argument.

Use leftAssoc1 if you have an initial value to be parsed first.

Implementation is based on chainReduce and map.
Type Parameters
- TToken
- TOptions
- TAcc
- TValue
Parameters
- acc: TAcc
  Initial value for the accumulator.
- p: Parser<TToken, TOptions, TValue>
  Parser for each next value.
- reducer: (
      acc: TAcc,
      v: TValue,
      data: Data<TToken, TOptions>,
      i: number,
      j: number,
  ) => TAcc
  Function to combine the accumulator and each parsed value.
  - (acc: TAcc, v: TValue, data: Data<TToken, TOptions>, i: number, j: number): TAcc
    Parameters
    acc: TAcc
    Accumulated value.
    
    v: TValue
    Value from each successful parsing.
    
    data: Data<TToken, TOptions>
    Data object (tokens and options).
    
    i: number
    Position before current match.
    
    j: number
    Position after current match.
    
    Returns TAcc
Returns Matcher<TToken, TOptions, TAcc>
