What is the output of the following? “`js function outer() { var x = 1; function inner() { var x = 2; console.log(x); } inner(); console.log(x); } outer(); “`

Accepted Answer

The output of the code is 2, 1 because the inner function declares a new variable x within its scope, which is separate from the x variable in the outer function.
