Empty constructors for TypedArrays are not allowed

[ltetzlaff]

Typescript currently does not support empty constructors of TypedArrays, as in mdn UInt8Array, thx to sindresorhus for pointing that out.

TypeScript Version: 2.7.0-dev.201xxxxx

Code

const x = new Uint8Array()

Expected behavior:
works
Actual behavior:
Error: Expected 1-3 arguments, but got 0.

This is an ES 2017 specific change, should go in a new file src/lib/es2017.typedArrays.d.ts and linked from https://github.com/Microsoft/TypeScript/blob/master/src/lib/es2017.d.ts.
