Course: Design Patterns in JavaScript
duration: 17 hours |
Language: English (US) |
access duration: 180 days |
Details
With this course you learn how to use Design Patterns in JavaScript efficiently. You'll start this course by exploring principles of good design and the three main categories of design patterns. Learners examine how to use constructors to create and initialize objects and how to use Factory and Abstract Factory to create different kinds of objects. Next, you'll discover how to implement Singleton, Prototype, and Builder patterns in Javascript. Examine how Singleton pattern is used for single object instantiation, how Prototype pattern is used for cloning, and how Builder pattern is used to construct complex objects. You'll discover how to implement common structural design patterns, Module and Revealing Module patterns, then examine how to set up helpers for the Facade pattern, and how to use it for AJAX requests and delve into use of Decorator and Mixin patterns.
Furthermore, you'll discover how to implement Flyweight, Adapter, Composite, and Proxy patterns to model structure between the components in a system. Examine inefficient memory usage, sharing memory, and centralized event handling with Flyweight pattern. You'll also learn how to set up publishers and subscribers and the role of Observer pattern in event handling, then learn how to trigger custom events in jQuery, use Observer pattern with custom events, iterate over elements in a collection, and use Iterators in jQuery. Finally, you'll explore the Mediator, State, and Command behavioural design patterns, including how to implement them for modelling communication between components.
Result
After completing this course, you are ready to implement Design Patterns in JavaScript in your daily work.

Design Patterns in JavaScript
Design Patterns in JavaScript: Getting Started
Explore the principles of good design and the three main categories of design patterns. Examine anti-patterns, including their uses and what to avoid while writing code. Discover how to install NodeJS and NPM for MacOS and Windows.
Design Patterns in JavaScript: Constructor, Factory, & Abstract Factory Creational Patterns
Explore the constructor, factory, and abstract factory creational patterns in JavaScript. Examine how to use constructors to create and initialize objects and how to use the factory and abstract factory to create different kinds of objects.
Design Patterns in JavaScript: Singleton, Prototype, & Builder Creational Patterns
Discover how to implement the Singleton, Prototype, and Builder patterns in JavaScript. Examine how the Singleton pattern is used for single object instantiation, how the Prototype pattern is used for cloning, and how the Builder pattern is used to construct complex objects.
Design Patterns in JavaScript: Module, Revealing Module, Façade, Decorator, & Mixin Structural Patterns
Discover how to implement common structural design patterns.
- Explore the Module and Revealing Module patterns, including how to
- implement private variables and functions with the Module pattern
- and best practices for using the Revealing Module pattern. Examine
- how to set up helpers for the Façade pattern, how to implement it,
- and how to use it for AJAX requests. Delve into the use of the
- Decorator pattern, including how to set up its functions and how to
- use it for dynamic customizations. Using the Mixin pattern in
- Underscore.js and for simulating multiple inheritance is also
- covered.
Design Patterns in JavaScript: Flyweight, Adapter, Composite, & Proxy Structural Patterns
Discover how to implement the Flyweight, Adapter, Composite, and
- Proxy patterns to model structure between the components in your
- system. Examine inefficient memory usage, sharing memory, and
- centralized event handling with the Flyweight pattern. Explore the
- possible burden on a client when the Adapter pattern isn't used and
- how to provide a consistent interface using an adapter. Using the
- Composite pattern in jQuery, and using the Proxy pattern to cache
- data and specify context are also covered.
Design Patterns in JavaScript: Observer & Iterator Behavioral Patterns
Discover how to implement the Observer pattern for communication
- and the Iterator pattern to work with collections. Examine how to
- set up publishers and subscribers and the role of the Observer
- pattern in event handling. Triggering custom events in jQuery,
- using the Observer pattern with custom events, iterating over
- elements in a collection, and using Iterators in jQuery is also
- covered.
Design Patterns in JavaScript: Mediator, State, & Command Behavioral Patterns
Explore the Mediator, State, and Command behavioral design patterns, including how to implement them for modeling communication between components. Discover how to perform valid state transitions, implement the State pattern in React, and execute and undo commands.
Course options
We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.
Optional practice exam (trial exam)
To supplement this training course you may add a special practice exam. This practice exam comprises a number of trial exams which are very similar to the real exam, both in terms of form and content. This is the ultimate way to test whether you are ready for the exam.
Optional practice lab
To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. The lab enviromentconsist of complete networks containing for example, clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
