What are JavaScript design patterns

JavaScript design patterns are reusable solutions to common problems in software design. These patterns can help developers create well-structured and maintainable code. Some of the most popular design patterns in JavaScript include Singleton, Module, Factory, Observer, and Prototype patterns.

Example: Module Pattern


        const Module = (() => {
            let privateVar = 'I am private';
            
            return {
                publicMethod: () => {
                    console.log(privateVar);
                }
            };
        })();

        Module.publicMethod(); // Output: I am private
