I have a problem

Question

I don't know but somehow js is not working on my vscode or maybe I am doing something wrong because it shows me a mistak when I code var= 10;
document.write(x); it says that document is not defined

Answer 1

Are you using vscode to execute js code?

document object is not available in runtime environments, that's why it says 'document' is not defined

Link your script with HTML and then load it in browser!

Answer 2

var x = 10
// var = 10

Answer 3

If there is no document (html), just output to console instead: console.log()
