how to determine if something is an object in javascript code example

Example 1: javascript check if variable is object

let myObject = {
	firstname: 'harry',
  	lastname: 'potter'
}
//check the typeof if, boolean, object, string etc...
console.log(typeof myObject);
if(typeof myObject === 'object') {
	console.log('this is object');

typeof yourVariable === 'object' // true if it's an object or if it's NULL.

// if you want to exclude NULL
typeof yourVariable === 'object' && yourVariable !== null
