Are variables statically or dynamically “scoped” in javascript?

Question

Or more specific to what I need:

If I call a function from within another function, is it going to pull the variable from within the calling function, or from the le

Answer 1

myVar=0;

function runMe(){
    myVar = 10;
    callMe();
}

function callMe(){
   addMe = myVar+10;
}

As far as the output is concerned myVar and addMe both will be global variable in this case , as in javascript if you don't declare a variable with var then it implicitly declares it as global hence when you call runMe() then myVar will have the value 10 and addMe will have 20 .
