I can't use js, why?

I updated unity this week and now, i can't add js script on my gameObjects : I just can add c# script. How can i use js?

 

You can still create JS via the Legacy submenu. JS is being deprecated from Unity and will eventually be removed.

 

I guess it was a matter of time until this happened.
JS is being removed at some point in the near future. You can either choose to stay on this version or switch to C#. (Which is fairly trivial for someone with a fair amount of programming experience)

Here is the blog post:

EDIT: I just realised they called it UnityScript in the blog post. How long have they done that?
(Its always been US to me )

 

Different Unity employees seem to refer to it by different names.

 

thank you
