JavaScript AJAX Basics (retiring) Programming AJAX Parsing JSON Data

Trying to follow along with Parsing JSON Data video but getting error

When I try to follow along with this video, including opening the console, I get an error message that appears to be rooted in the 4th line of my widget.js, and specifically with the content inside the console.log(). 

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if (xhr.readyState === 4) {
    console.log(typeOf xhr.responseText);
  }
};
xhr.open('GET', 'data/employees.json');
xhr.send();

When I put my cursor over the content of my console.log, I get the following msg:

"Uncaught SyntaxError: missing ) after argument list"

I'm not seeing why there's an error here, and hoping another pair of eyes can spot it.

The typeof operator should be written all in lowercase, not in camelCase like it is in your code. If you change its name like this:

console.log(typeof xhr.responseText);

Then that will likely fix that error.
