I keep getting ['alert' is not defined] error on Atom, but my code works in the browser.
Can anyone tell me what this means? What do I do with this warning and how do i fix it?
Thank you so much!

Courses Plus Student 116 PointsHi Brandon, thank you so much for your answer! 🙏
This is what I'm trying to do:
alert("Hello, World!");
console.log("hello from console.");
alert("Thanks for visiting!");
document.write("<h1>Welcome to my space!</h1>");
The thing is, it worked previously. But for some reason I started getting the "invalid regular expression flags" warning for every file I opened including a new one. Someone advised to re-install Atom, so I did and now it's a different kind of error LOL 🤦♀️
My apologies if my questions or concerns seem dumb. I'm a JS newbie :D
Thanks, again!

The 'is not defined' message typically means that you're trying to access the value of an undeclared variable.
For example:
const name = "Brandon"
print(firstName) // <= this statement would cause an error because I have yet to declare a variable called firstName
If you could provide a link to your code so that I can run it myself, I might be able to help you figure out what specifically is leading to your error/warning.
