Checks if the passed value is an object or not.

• Uses the Object constructor to create an object wrapper for the given value.
• If the value is null or undefined, create and return an empty object.
• Otherwise, return an object of a type that corresponds to the given value.

const isObject = obj => obj === Object(obj);

isObject([1, 2, 3, 4]); // true
isObject([]); // true
isObject(['Hello!']); // true
isObject({ a: 1 }); // true
isObject({}); // true
isObject(true); // false
