JavaScript: Get a boolean determining if the passed value is an object or not

JavaScript fundamental (ES6 Syntax): Exercise-194 with Solution

Write a JavaScript program to get a boolean determining 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.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
const isObject = obj => obj === Object(obj);

console.log(isObject([1, 2, 3, 4]));
console.log(isObject([]));
console.log(isObject(['Hello!']));
console.log(isObject({ a: 1 }));
console.log(isObject({}));
console.log(isObject(true));

Sample Output:

true
true
true
true
true
false
