HOW

traverse is exported as a function with helper utilities (explode, hasType, cheap, clearNode)
traverse walks AST nodes and triggers visitor callbacks for specific node types such as Identifier and FunctionDeclaration
traverse executes enter and exit lifecycle hooks in correct order for AST nodes
traverse supports path.scope binding inspection and scope-level symbol renaming
traverse supports path.skip to bypass child node traversal and path.stop to halt traversal
traverse passes custom visitor state and context objects across AST nodes
traverse supports AST mutation with path.remove and path.replaceWith
traverse.hasType quickly detects existence of AST node types without full traversal
traverse.explode normalizes multi-type visitor keys into exploded visitor maps
traverse.cheap iterates over all AST nodes with a simple callback function
visitors.merge combines multiple visitor definitions into a single visitor map
traverse exports NodePath and Scope constructor classes
