/**
 * A very jank function to determine if an object can be the target of Reflect.construct.
 * Unfortunately, many functions have a constructor in their prototype. These
 * functions are treated like classes due to JavaScript's poor distinction between
 * classes and functions.\
 * Typescript can enforce "new" keyword usage, but overriding the type
 * allows you to `new isConstructor()` despite this function not intended to be
 * used with the `new` keyword.
 * #### NOTE: Only works when targeting ES6/ES2015 or later.
 * > If your project or a dependent project is compiled to < ES6, this function will always return `false`; classes and constructors were introduced in ES6/ES2015.
 * @param object Anything.
 * @returns `true` if the {@link object} is a constructor. Else, `false`.
 * @since 3.0.0
 * @see https://stackoverflow.com/a/49510834
