Tell us what’s happening:

In this piece of code,I dont see the fucntions fun1() and fun2() being called, yet I see the output - why ?

Your code so far


// Declare your variable here

var myGlobal = 10;

function fun1() {
// Assign 5 to oopsGlobal Here
oopsGlobal = 5;
}

// Only change code above this line
function fun2() {
var output = "";
if (typeof myGlobal != "undefined") {
  output += "myGlobal: " + myGlobal;
}
if (typeof oopsGlobal != "undefined") {
  output += " oopsGlobal: " + oopsGlobal;
}
console.log(output);
}

The tests run the functions, which in turn calls the console log
