Function: walkAst()
walkAst(
root,visitor):void
Performs a non-recursive traversal of an ESTree AST.
Parameters
• root: Node
Root AST node to start the traversal from.
• visitor: AstVisitor
Callbacks invoked when nodes are entered or left.
Returns
void
Remarks
- If it returns
WALK_STOP, the entire traversal is halted. - Why did I not use some AST walker library instead?: They're too slow.
