Get type of object in JavaScript - ECMAScript 2021

To get the type of an object in JavaScript ECMAScript 2021, you can use the typeof operator. The typeof operator returns a string indicating the type of the operand. Here are some examples:

1. Checking for a string:

let str = 'Hello World';
console.log(typeof str); // Output: string

2. Checking for a number:

let num = 123;
console.log(typeof num); // Output: number

3. Checking for a boolean:

let bool = true;
console.log(typeof bool); // Output: boolean

4. Checking for an object:

let obj = {
  name: 'John Doe',
  age: 30
};
console.log(typeof obj); // Output: object

5. Checking for a function:

function greet(name) {
  console.log('Hello, ' + name + '!');
}
console.log(typeof greet); // Output: function

6. Checking for an array:

let arr = [1, 2, 3];
console.log(typeof arr); // Output: object
console.log(Array.isArray(arr)); // Output: true

Note: Array.isArray is a method to check if the given object is an array. It returns true if the object is an array, otherwise, it returns false.
