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 constructor pattern?

As a JavaScript developer, you may have encountered "constructors" at some point. These are special functions that initialize objects with specific properties and methods. 

The "constructor pattern", as the name defines, is a *class-based* pattern that uses the *constructors* present in the class to create specific types of objects.

## Example

There are many ways to create objects in JavaScript, such as using the `{}` notation or using  `Object.create`. 

However, in JavaScript, the use of the "constructor" pattern is very popular as it can create multiple objects of a specific kind. Let's take a look at an example:
