URLSearchParams accepts an object in the constructor

[vkrol]

Hello!

The current version of URLSearchParams accepts an object in the constructor.
Proof: https://codesandbox.io/s/urlsearchparams-object-tdo8i.
The corresponding change in the specification was made on 11 Jan 2017: whatwg/url#175 (comment).

I looks like it has decent browser support, too.
