Global Scope and Functions

Summary

Scope refers to the visibility of variables.
Variables with a global scope can be accessed anywhere using JavaScript code.
Variables which are declared without the var keyword are automatically created in the global scope.

Final Code

// Declare the myGlobal variable below this line


function fun1() {
  // Assign 5 to oopsGlobal Here
  oopsGlobal = 5;
}
var myGlobal = 10;
// 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);
}
