Why is a variable without the 'var' keyword not in the global scope in the chrome console?

Question

Because I am not using the var keyword why is the variable 'local' not in the global scope in the chrome console?

function test(){
local = true;
};

console.log(local);//Uncaught ReferenceError: local is not defined

Answer 1

It is simply because the test function is never called so the local variable is never created due to which it throws error

Answer 2

It will be available once test() is invoked
