import { prefix } from "https://deno.land/x/froebel@v0.21.3/mod.ts";
Returns str prefixed with prefix. Optionally, allows prefxing in camel
case, i.e. prefix('foo', 'bar', 'camel') => 'fooBar', or snake case, i.e.
prefix('foo', 'bar', 'snake') => 'foo_bar'.
The result is strictly typed, so prefix('foo', 'bar') will return the type
'foobar', not just a generic string.
