4,367 Points'console' was used before it was defined
I am learning J.S. using Brackets.
When I was trying to use console.log, it tells my there is a JSLint Problem, 'console' was used before it was defined.
I don't know what could cause this happen and how to solve it, please help.
Thank you .

However, when you run your script in the browser, you should get output in the DevTools console.
Hope that helps.

If I understand clearly, I don' t have to worry about about the warning, and it will just display normally if I run it in my browser?
