This commit introduces a custom error object to provide additional
context for errors throwing during parsing and compiling operations,
improving troubleshooting.
By integrating error context handling, the error messages become more
informative and user-friendly, providing sequence of trace with context
to aid in troubleshooting.
Changes include:
- Introduce custom error object that extends errors with contextual
information. This replaces previous usages of `AggregateError` which
is not displayed well by browsers when logged.
- Improve parsing functions to encapsulate error context with more
details.
- Increase unit test coverage and refactor the related code to be more
testable.
This commit applies `strictNullChecks` to the entire codebase to improve
maintainability and type safety. Key changes include:
- Remove some explicit null-checks where unnecessary.
- Add necessary null-checks.
- Refactor static factory functions for a more functional approach.
- Improve some test names and contexts for better debugging.
- Add unit tests for any additional logic introduced.
- Refactor `createPositionFromRegexFullMatch` to its own function as the
logic is reused.
- Prefer `find` prefix on functions that may return `undefined` and
`get` prefix for those that always return a value.
