A Babel plugin that marks CallExpression AST nodes which are tail calls and/or proper tail calls.
Two properties are added to CallExpression nodes, tailCall and properTailCall.
-
If
tailCallis set totruethen the CallExpression is in tail position. -
If
properTailCallis set totruethen the CallExpression is both in tail position and is a "Proper Tail Call".
This plugin is designed to be used with your own plugins which look for the tailCall and properTailCall properties within any CallExpression AST node.
