set-alias to executable plus command-line option

Question

In PowerShell, & "C:\Program Files\Java\jre-9.0.1\bin\jjs.exe" --language=es6 gives me access to the Nashorn interpreter for ES6. I want to create an alias for exactly this. How can I create an alias to start this process with the desired command-line option?

Aliases don't support that. Define a function instead: `function nashorn { & "C:\Program Files\Java\jre-9.0.1\bin\jjs.exe" --language=es6 }` — Mathias R. Jessen, Dec 30 '17 at 20:49
@MathiasR.Jessen Thanks; I was aware of this solution. Can you say simply why this is beyond the scope of aliases? (I'm pretty new to PowerShell.) Thanks. — Alan, Dec 30 '17 at 21:22

Putting Mathias's comment as an answer. You should create it as a function and finally you can call the function wherever you need it just by the name.

function call-nashorn 
{ 
    & "C:\Program Files\Java\jre-9.0.1\bin\jjs.exe" --language=es6 
}
call-nashorn
