  • Recognize and apply design patterns
  • Refactor existing designs to use design patterns
  • Reason about applicability and usability of design patterns

Course Summary

This course offers an extensive summary of Design Patterns in JavaScript from a useful viewpoint. This Design Patterns in JavaScript course in particular covers patterns using:

  • The most recent variations of the JavaScript programming language
  • Use of contemporary programming libraries and structures
  • Use of contemporary developer tools such as JetBrains WebStorm
  • Discussions of pattern variations and alternative techniques

This Design Patterns in JavaScript course supplies a summary of all the Gang of 4 (GoF) design patterns as laid out in their critical book, together with modern-day variations, modifications, discussions of intrinsic use of patterns in the language.

What are Design Patterns?

The initial book GoF book utilized C++ and Smalltalk for its examples, however, ever since, design patterns have actually been adjusted to every programming language you can possibly imagine: C#, Java, Swift, Python and now– JavaScript!

The appeal of design patterns is immortal: we see them in libraries, a few of them are intrinsic in programming languages, and you most likely utilize them every day even if you do not recognize they exist.

Design Patterns are reusable solutions to typical programming issues. They were promoted with the 1994 book Design Patterns: Elements of Reusable Object-Oriented Software by Erich Gamma, John Vlissides, Ralph Johnson and Richard Helm (who are typically called a Gang of 4, for this reason the GoF acronym).

What Patterns Does This Course Cover?

This Design Patterns in JavaScript course covers all the GoF design patterns. Here’s the complete list of what is covered:

  • STRONG Design Concepts: Single Duty Concept, Open-Closed Concept, Liskov Replacement Concept, User Interface Partition Concept and Reliance Inversion Concept
  • Creational Design Patterns: Home Builder, Factories (Factory Technique and Abstract Factory), Model and Singleton
  • Structrural Design Patterns: Adapter, Bridge, Composite, Designer, Fa├žade, Flyweight and Proxy
  • Behavioral Design Patterns: Chain of Duty, Command, Interpreter, Iterator, Mediator, Memento, Observer, State, Technique, Template Approach and Visitor

Who Is the Course For?

This Design Patterns in JavaScript course is for JavaScript developers who wish to see not simply textbook examples of design patterns, however likewise the various variations and techniques that can be applied to execute design patterns in a contemporary method. The usage of Symbol.iterator enables things (consisting of iterator things) to be iterable and lets scalar items masquerade as if they were collections.

Presentation Style

This course exists as a (huge) series of live presentations being performed in JetBrains WebStorm and provided utilizing the Kinetica rendering engine. Kinetica eliminates the visual mess of the IDE, making you concentrate on code, which is rendered completely, whether you are viewing the Design Patterns in JavaScript course on a cinema or a cellphone.

The majority of demos are single-file, so you can download the file connected to the lesson and run it in WebStorm, Atom or another IDE of your option (or simply run them from the command-line).

This course does not utilize UML class diagrams; all of the demos are done through live coding.

Who this course is for:

  • Software engineers
  • Web developers
  • Designers
  • Architects
