The ultimate guide to coding interviews: Learn and practice JavaScript design patterns tested by FAANG engineers. Get interview-ready in just a few hours with battle-tested solutions.

If you're an experienced developer, chances are your interviewer won't ask you about language syntax. Instead, they'll focus on things that test your understanding of software architecture, and how capable you are at finding optimized solutions to given problems. 

That’s where a strong understanding of design patterns comes in handy. It's often useful to be able to draw on established patterns instead of reinventing the wheel.

In this course, you will learn how to effectively deploy design patterns to answer interview questions. The course is divided into four sections: Creational Patterns, Structural Patterns, Behavioral Patterns, and Architectural Patterns. Each section has its own set of design patterns which you’ll learn to use through various challenges. 

Every challenge contains a detailed solution explanation. By the end of this course (and with some practice), you will be able to confidently use design patterns to tackle advanced coding interview questions in JavaScript.

JavaScript Design Patterns for Coding Interviews

In this chapter, we will discuss creational patterns. As the name implies, these patterns provide optimized object creation techniques. They help cater to the design and complexity problems that might occur when using the basic approach. They also help  control the creation of objects.

The creational patterns we will cover in this chapter include:

* *Factory pattern*

* *Constructor pattern*

* *Singleton pattern*

* *Builder pattern*

* *Prototype pattern*

* *Abstract pattern*


This lesson discusses what creational patterns are and the patterns that we'll cover in this chapter.
