How to create a private method of a class in JavaScript?

Programming Bytes

Overview

The private method of a class can only be accessible inside the class. The private methods cannot be called using the object outside of the class. If we try to access the private method outside the class, we'll get SyntaxError .

Our private method can be declared by adding the # before the method name.

Example

Console
Creating private method in class

Explanation

Line 6: We have created a new class with the name ClassWithPrivateMethod.

Lines 7–9: We declare a private method with the name #privateMethod.
