Javascript Odd Scoping Behavior

Question

I\'ve been going through Javascript function scope and have run into this:

var scope = \"global\";

function f(){
    console.log(scope);

    var scope = \"loca         


        

Answer 1

If you omit the var statement, the first log uses the global variable, which is set with the string "global". There is no other local variable and no hoisting.

1. First log: global variable scope set with "global" content
2. Assignment of new string for the same global variable
3. Second log: global variable scope set with "local" content
