Global Scope and Functions

/* Global Scope and Functions
In JavaScript, scope refers to the visibility of variables. Variables which are defined outside of a function 
block have Global scope. This means, they can be seen everywhere in your JavaScript code.

Variables which are used without the var keyword are automatically created in the global scope. This can create 
unintended consequences elsewhere in your code or when running a function again. 
You should always declare your variables with var.

Using var, declare a global variable myGlobal outside of any function. Initialize it with a value of 10.

Inside function fun1, assign 5 to oopsGlobal without using the var keyword. */

// 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);  // Output equals myGlobal: 10 oopsGlobal: 5
}
