Solution is working, however still have 3 line errors?

I was doing the Variable Challenge and got it to work perfectly. However in my text editor it said document.write, alert, and prompt were used before they were defined. What does this mean and should I just ignore these?

document.write, prompt and alert is not a part of JavaScripts native library, which we always can use when writing javascript code. They belong to the browser API, i.e., they only work when you run them in a browser environment. For the code to work correctly you need to find a JavaScript interpreter which runs in a browser environment. An example of such an interpreter could be this online interpreter.
