Is there any equivalent of "using" in JavaScript?

Unity Engine

I’m calling a C# script (LitJson) from Jav. Is there an equivalent of “using namespace” in JavaScript so I don’t need to type LitJason.JsonFoo constantly?

Thanks!

@import is the counterpart to using

Many thanks! Is “import” documented anywhere? I feel like an idiot for not finding it, and I’m wondering if I missed an important doc somewhere (I’m very newb at Unity so please forgive me!)

Interestingly I found that

@script RequireComponent(Foo)
import LitJson;

gave me a syntax error “expecting EOF” but

import LitJson;
@script RequireComponent(Foo)

worked fine.
