This course is for JavaScript developers who are preparing for their interviews and want to learn about the types of design patterns. The course is divided into four sections, each explaining one category of the design pattern. The types covered in this course include creational, structural, behavioral, and architectural design patterns. Each pattern is explained with the help of examples and is followed by a challenge and its solution review.
