(`typescript-go/internal/ast`): Complete AST node definitions and utilities + +- **Parser Package** (`typescript-go/internal/parser`): TypeScript/JavaScript parser implementation + +- **Scanner

Package** (`typescript-go/internal/compiler`): Program compilation and management + +- **Rules Package** (`rslint/internal/rules`): ESLint-compatible linting rules + +## AST Node Architecture + +### Core Node Structure + +The AST is built around a central `Node` struct that represents all syntax elements: + +```go +type Node struct { + Kind Kind // Node type identifier + Flags NodeFlags // Node-specific flags + Loc core.TextRange // Source location information + id atomic.Uint64 // Unique node identifier + Parent *Node // Parent node reference + data nodeData // Type-specific data +} +``` + +### Node Data Interface + +All AST nodes implement the `nodeData` interface, providing polymorphic behavior: + +```go +type nodeData interface { + AsNode() *Node + ForEachChild(v Visitor) bool + IterChildren() iter.Seq[*Node] + Clone(f NodeFactoryCoercible) *Node + VisitEachChild(v *NodeVisitor) *Node + Name() *DeclarationName + Modifiers() *ModifierList + // ... additional methods +} +``` + +### Node Factory System + +The `NodeFactory` manages node creation and pooling for performance: + +```go +type NodeFactory struct { + hooks NodeFactoryHooks + arrayTypeNodePool core.Pool[ArrayTypeNode] + binaryExpressionPool core.Pool[BinaryExpression] + blockPool core.Pool[Block] + callExpressionPool core.Pool[CallExpression] + // ... pools for all node types + nodeCount int + textCount int +} +``` + +## Complete AST Node Types Reference + +### Kind Enumeration + +The `Kind` type defines all possible AST node types: + +```go +type Kind int16 + +const ( + // Trivia and
