Can I use erb code inside a .js file?

Hi all,

Can I have a ruby code inside a java script function written in .js
file?
When I tried it, i got an error.
e.g. consider following function inside myscript.js file

myscript.js
function sayHi
{
<%name=“xyz”%>;
alert(‘HI <%=name%>’);
}

But this works if I have above function in a rhtml file inside
tag.

Any inputs in this regard will be really helpful.

Thanks and Regards,
Medha.
