How Can I Effectively Determine if a Value is an Object in JavaScript?

Tricks to check whether a value is an object in JavaScript

JavaScript provides several methods to check whether a value is an object. The simplest of these is to use the typeof operator.

Usage:

Use the typeof operator and compare the results it returns. If typeof x equals "object", then x is an object (other than a function) or null.

Example:

typeof {} === "object"; // true
typeof [] === "object"; // true
typeof null === "object"; // true
typeof 1 === "object"; // false

Exclude nulls, arrays and functions:

If you wish to exclude null, arrays and functions, more complex conditions can be used:

typeof x === 'object' && !Array.isArray(x) && x !== null

Example:

typeof {} === "object" && !Array.isArray({}) && {} !== null; // true
typeof [] === "object" && !Array.isArray([]) && [] !== null; // false
typeof null === "object" && !Array.isArray(null) && null !== null; // false

By using these methods, you can easily The code checks whether the value is an object and handles it accordingly as needed.
