/* Prior art: this utility was created for https://github.com/11ty/eleventy/issues/2214
* Inspired by implementations from `is-what`, `typechecker`, `jQuery`, and `lodash`
* `is-what`
* More reading at https://www.npmjs.com/package/is-what#user-content-isplainobject-vs-isanyobject
* if (Object.prototype.toString.call(value).slice(8, -1) !== 'Object') return false;
* return value.constructor === Object && Object.getPrototypeOf(value) === Object.prototype;
* `typechecker`
* return value !== null && typeof value === 'object' && value.__proto__ === Object.prototype;
* Notably jQuery and lodash have very similar implementations.
* For later, remember the `value === Object(value)` trick
