Hi freeCodeCamp forum users. I’ve learned about the basics of JavaScript.

But, what does the typeof keyword mean in JS? And what does it means??

I don’t know how to use the typeof keyword, like this:

console.log(typeof null);
var aNumber = 5;
console.log(typeof aNumber);

Please answer. :smiley:

Thank you!
