When you post code in the forum, you need to format it. To do so you can either select all the code and click the </> button, or type 3 backticks ``` on a separate line both before and after the block of code.

I have done it for you this time.

= is an assignment so will always be true. That’s why you always get the same result.

== is the equality operator (or ‘===’).

Your conditional statement should use the equality operator(==) and then when you assign a value use the assignment operator (=).

It would also be better to remove the onclick from the html and do it from the js file instead where it belongs…

Also tidy your brackets up on the if/else code.

e.g.

No! You started to learn JavaScript :slight_smile: Java is a completely different language :wink:

“Java is to Javascript as Pen is to Penguin.”

Though I will say, if this is your first week with Javascript, and you came up with this code on your own, you’ve got a very strong foundation.

(EDIT: I cant read. Go me.)
