JavaScript JavaScript Basics (Retired) Introducing JavaScript The JavaScript Console

Javascript practice not working.

I'm trying to practice the javascript stuff that I learned but when I make an html document and link the javascript and put (alert("I'm nice");) into the file and run it. I get an error message that says... JSLint Problem - 'alert' was used before it was defined... What am I doing wrong? What does this error mean? What is JSLint Problem?

Hi Terry,

I think it's because you are wrapping your alert in parenthesis. Try just using alert("I'm nice"); and see if that works.

Hey man, how are you getting on with this?

Can you show us how you're linking the JS and the code you're using?

is this what's in your code: (alert("I'm nice");)

It should be: alert("I'm nice");
