> Determines whether a value is a URLSearchParams instance.

Works cross-realm/iframe and despite Symbol.toStringTag.

Installation

Node.js >= 8 is required. To install, type this at the command line:
``shell
npm install is-urlsearchparams
`

Usage

`js
const isURLSearchParams = require('is-urlsearchparams');

isURLSearchParams('param=value'); //-> false
isURLSearchParams(new URLSearchParams('param=value')); //-> true
`

Optionally, acceptance can be extended to incomplete URLSearchParams implementations that lack entries, sort and values methods (which are common in many modern web browsers):
`js
const params = new URLSearchParams('param=value');

console.log(params.sort); //-> undefined

isURLSearchParams.lenient(params); //-> true
``
