Use external object when defining a variable identical to class name

[liorgonnen]

three.js contains a definition file called AudioContext.d.ts.

The file contents is:

export const AudioContext: AudioContext;

This is being translated to:

external var AudioContext: AudioContext

There are two issues here:

1. The AudioContext class doesn't exist (it's part of the Web Audio API)
2. This is the issue I want to focus on here: Even if the class was defined (or if I add it manually), we still get a conflicting declarations error.

Could this be translated into either:

external object AudioContext

or

external interface AudioContext

(I'm currently using the latter here and here

Interesting. I wonder what does original definition stands for in first place

 export const AudioContext: AudioContext;

I have to move it to 0.5.9 since there's a need to investigate what would be the better option.
