Tell us what’s happening:
Am I doing anything wrong with this code?

  **Your code so far**

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

Instructions:

Inside function fun1 , assign 5 to oopsGlobal without using the var , let or const keywords.

Where did you assign 5 to oopsGlobal?

Instructions:

Using let or const , declare a global variable named myGlobal outside of any function. Initialize it with a value of 10 .

What key word did you use to delcare the global variable myGlobal?

Please clarify your question/concern.
Are you just asking for a code review or are you trying to fix a bug (or other)?

myGlobal should be declared using the let or const keywords
This is the thing I need to have checked.

“var” is the variable for ‘myGlobal’
