Object parse using json-bigint doesn't have Object function

`var JSONbigString = require(‘json-bigint’);

var key = ‘{ “key”: 1234567890123456789 }’; var withString = JSONbigString.parse(key);

console.log(Function.prototype.toString.call(withString.constructor));`

Result `console.log(Function.prototype.toString.call(withString.constructor)); ^

TypeError: Function.prototype.toString requires that ‘this’ be a Function at toString (<anonymous>) at Object.<anonymous> (Ravi/office/mix/check.js:6:41) at Module._compile (internal/modules/cjs/loader.js:776:30) at Object.Module._extensions…js (internal/modules/cjs/loader.js:787:10) at Module.load (internal/modules/cjs/loader.js:653:32) at tryModuleLoad (internal/modules/cjs/loader.js:593:12) at Function.Module._load (internal/modules/cjs/loader.js:585:3) at Function.Module.runMain (internal/modules/cjs/loader.js:829:12) at startup (internal/bootstrap/node.js:283:19) at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)`

Expected

function Object() { [native code] }

When you use normal JSON.parse you will get the constructor as expected.

use the last version instead

npm install --save json-bigint@0.4.0

After update to 1.0.0, lots of weird problem occurred. I’ve never mind some library do some prototype pollution. But there is no options to keep the compatibility to the older version.

I filed a PR to add an option to preserve prototype properties on the parsed objects: https://github.com/sidorares/json-bigint/pull/47

var JSONbig = require('json-bigint');
var JSONBigInt = JSONbig({ objectBaseClass: Object }); // default is null
var key = '{ "key": 1234567890123456789 }';
// should not result in TypeError thanks to `objectBaseClass: Object`
console.log(Function.prototype.toString.call(withString.constructor));`

Upd.: oh, I thought built-in BigInt support was not available in v0.4.0, but apparently it is, so, yeah, better to just stick to v0.4.0
