Hacker News post explains parser combinators with TypeScript examples
Why it matters for readers: Provides a hands-on example of how parsers can be combined to read and structure text.
- The post presents a Parser<T> type as a function from an input string to a pair of a parsed value and the remaining string.1
- Examples include pHello, pIgnoreWhitespace and pInteger that parse parts of strings such as "Hello 100".1
- Parsers are composed using pSeq to create a Parser of a tuple and then transformed with pMap to build structured objects.1
- The examples show step-by-step how each parser consumes the input and passes the remainder to the next parser.1
