Split `TopDownParser` into separate files for better modularity and maintainability. Added implementations for expressions, declarations, and statements handling.
update grammar rules for assignment and cast expressions Refined `AssignmentExpression` grammar to include optional "Operator" and updated `CastExpression` to support dynamic `TypeValue`.
Added validation to throw `ParserException` when no `:` or `=` follows an argument name
simplify expression parsing logic Allow end call expr list with comma
replace `LeftHandSideExpression` with `MemberExpression` in `AssignmentExpression` and related grammar adjustments
simplify declaration parsing logic Replaced `AddToDeclaration` with `DeclarationAssignmentExpression` Prohibited undefined vars like `let x` grammar-wise
- Replaced null returns with `ParserException` for better error handling - Extracted `CurrentIsStatement` for cleaner parsing logic - Updated grammar to improve clarity on `MemberExpression` Closes #233
Specify value of expected tokens for certain types
- Updated `TokenTypes` to separate `Assign` and `Operator` patterns, improving token categorization. - Added `Distinct()` to `TokenTypesProvider` for unique token handling. - Adjusted `GeneratedRegexContainer` to include `ExplicitCapture` for better regex performance. Closes #233
Standardized null safety for parent scopes across AST nodes, replacing direct access with conditional checks and fallback to `Scope.Empty`.
Desugar Compound Assignment Closes #233
