Can't Access Variable from other Javascript File

I am trying to access a variable from another file in JavaScript, and I'm not able to. When I try to print that variable out, for example, Intellisense suggests the variable. However, when I actually run it, I get the error Uncaught ReferenceError: myVariable is not defined The variable is definitely declared in my file ('homePage.js').

I thought that all variables in Javascript were global, so I'm not sure why this is happening. All my files are in the same folder. Do I need to import something or am I just doing something completely wrong?

Thank you!

Maybe you are trying to access the variable value when your file still not loaded in the browser. You can check this using window.onload

window.onload = function() {
  console.log('myVariable', myVariable);
  // or execute some function that use the variable
}

You can also move variables into session state / cookie and pull it back into the other script from there.
