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 structural patterns. As the name implies, these patterns are concerned with object relationships and the structure of classes or objects. They help to add new functionality without having to modify the entire system. They ensure that if one part of a system changes, the whole system does not change with it.


The structural patterns we will cover in this chapter include:


* *Decorator pattern*

* *Facade pattern*

* *Adapter pattern*

* *Bridge pattern*

* *Composite pattern*

* *Flyweight pattern*

* *Proxy pattern*

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