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

## What is the bridge pattern?
 
The bridge pattern allows separate components with separate interfaces to work together. It keeps an object's interface separate from its implementation, allowing the two to vary independently. 

An example is controlling an air conditioner with a remote. The air conditioners can be of different types and each of them is controlled by a different remote. The remotes can vary, that is, a new one with better features can be introduced, but that won’t make any changes to the air conditioner classes. The same goes the other way round. The bridge pattern allows input and output devices to work together but vary independently.
