Basic JavaScript - Global Scope and Functions

Tell us what’s happening:
Hi Team, first time I’ve posted here. I’ve done every search, I’ve watched the video (which types var, not const or let, but that difference was clear) and everywhere says the same: define with: const myGlobal = 10; \ but when I type this, along with it’s second oppsGlobal = 5; I received the fail message- myGlobal should be defined.

  • Failed: myGlobal should be defined
  • Failed: myGlobal should have a value of 10
  • Passed: myGlobal should be declared using the let or const keywords
    Failed: oopsGlobal should be a global variable and have a value of 5

I’ve tried const myGlobal = [10]; as well as const myGlobal = “10” (though even I knew that wouldn’t work. I’ve checked w3schools and all resources available here, everyone writes it the same, but it still says it’s not defined. I can’t see what I’m doing wrong. Sorry to trouble all.

Your code so far

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

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

This can be closed now. Somehow I solved it, but it seems the only thing i changed was i removed the “;”

// Declare the myGlobal variable below this line
const 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);
}
