Question

is there a way to access the value of shadowed variable a in the scope of x()

Answer 1

Read this You Don't Know JS the Scope & Closures part, its well explaind

Try this:

 function x () { a = 1; function foo() { /* when you write a = 2, you are assining 2 to the global a */ var a = 2; console.log("global a", window.a); console.log("local a", a); } foo(); }; x(); console.log(window.a);
