Basic JavaScript - Global Scope and Functions

Tell us what’s happening:
Describe your issue in detail here.
We are nowhere calling the functions fun1() and fun2(), like we call in c/cpp/java. So how are they executed automatically?

Your code so far

// Declare the myGlobal variable below this line
//let myGlobal=10;

function fun1() {
  // Assign 5 to oopsGlobal here
  oopsGlobal=5;
  //console.log(oopsGlobal);
}

// Only change code above this line

function fun2() {
  let output = "";
  if (typeof myGlobal != "undefined") {
    output += "myGlobal: " + myGlobal;
  }
  if (typeof oopsGlobal != "undefined") {
    output += " oopsGlobal: " + oopsGlobal;
  }
  console.log(output);
}
