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 abstract pattern?

To understand the abstract pattern, let's go back to the [factory pattern](https://www.educative.io/courses/javascript-design-patterns-for-coding-interviews/factory-pattern). We use the factory pattern to create multiple objects from the same family without having to deal with the creation process. The abstract pattern is similar; the difference is that it provides a constructor to create families of related objects. It is abstract, meaning it does not specify concrete classes or constructors.
