LET ME SHARE MY KNOWLEDGE WITH YOU
I’ve been coding for a long time. At the age of 7, in the early 90’s, I got my first pc and a few days later I became an avid gamer. I have always surrounded myself with coders. I remember at 10 years old my cousin managed to hack into a bank’s system. I still recall the days of floppy disks and playing “Doom”, “Duke Nukem” and of course one of my all-time favorites, “Red Alert”.
I’ve always been around computers, and that’s what makes my teaching style direct, to-the-point, and powerful!
Now, why did I create a course on prototypes?
Prototypes are a fundamental concept of JavaScript. They are used to implement inheritance, object creation, and other important features. It is therefore crucial that you understand prototypes – what they are, why they are there, how to use them, how to create them, and when to use them!
Understanding JavaScript is ongoing process. To give you a foot up, I’ve structured an all-encompassing, focused course on JavaScript prototypes, which I deliver to you in a way that will benefit you the most. My course teaches you “why” things work and not just “how” to do something mindlessly.
What this course covers?
-
It starts at the beginner level of what JavaScript prototypes are
-
It then goes more in-depth by teaching you how to leverage the power of prototypes to create objects with multiple levels of inheritance
-
You’ll learn how to create objects, starting from the basics of object literals to more complex pseudo-classical inheritance patterns
-
Learn the difference between class-based languages (like Java, C#, C++) and prototypal-based languages like JavaScript
-
Learn the different instantiation patterns, such as functional instantiation, functional-shared, prototypal, pseudo-classical and pure classical
-
Master the differences between [[Prototype]] and __proto__ and the .prototype property
Literally this course everything you need to know about prototypes in JavaScript, all in one place 🙂
All the strategies I teach follow timeless coding principles and tactics.
WHAT ARE PROTOTYPES?
JavaScript was created by a guy called Brendan Eich in the mid-1990s. Eich decided to make JavaScript a prototype-based language because he wanted to create a language that was easy to learn and use. He wanted to create a language that was powerful and flexible, and he believed that prototypes were the best way to achieve this.
Prototypes are a powerful feature of JavaScript, because they allow you to reuse code, create complex object hierarchies, and implement inheritance in a simple and efficient way. However, prototypes can also be confusing,and they can make it difficult to understand how JavaScript works.
Despite the challenges, the benefits of prototypes outweigh the drawbacks.
Q: The million dollar question is “why does learning about prototypes matter?”
A: It matters because EVERY object in JavaScript has a [[Prototype]] property. It is this [[Prototype]] property that is often referred to as the “prototype”. By mastering prototypes, you can create complex objects that are extremely memory efficient – improving your website’s speed.
The prototype itself is also an object … which means that it also has a [[Prototype]] property. Can you begin to see that there’s a prototype “chain” forming? You can think of the prototype chain as a linked list of objects, where each object in the list has a pointer to the next object in the chain.
This is the reason why all objects you use and create have inbuilt properties and methods that you can access. This is why:
-
strings have toUpperCase() and toLowerCase()
-
arrays have sort(), map(), push() and filter()
-
numbers have toFixed(), toPrecision(), parseFloat()
-
…
You get the idea.
Why is learning about prototypes useful?
By understanding how prototypes work, how they are created, and how to set them up yourself, you’ll be able to create objects that inherit properties and methods from other objects, without having to explicitly define them.
This makes it possible to reuse code and create complex object hierarchies in a simple and efficient way.
Can you begin to see how powerful prototypes are and how essential it is today?
Knowing the power of how to use prototypes in JavaScript is crucial if you want to become a serious fullstack developer, as it will allow you to build complex data types and web apps.
Creating objects can get tricky at times, and I don’t dispute this, but with correct training which includes explaining the fundamentals of prototypes and object creation in a simple way, you will, like me, learn to master and love JavaScript’s dynamic approach to object creation.
If you want to become a full stack web developer, you need to knowabout prototype’s and that’s what this course is all about.
WHY IS UNDERSTANDING PROTOTYPES IMPORTANT?
-
JavaScript is built on prototypes
-
To master JavaScript, you need to master prototypes
-
Prototypes is a way to implement object-oriented programming
-
Prototypes allow you to extend existing objects
-
Prototypes allow you to implement inheritance in JavaScript
-
Prototypes allow you to create custom object constructors
-
Prototypes allow you to understand the JavaScript engine better
-
Ultimately, by understanding how prototypes work, you can write more efficient and reusable code.
After completing this ultimate prototypes course, you will certainly be knowledgeable, confident and able to manage or help others create objects in the most optimal way.
WHAT THIS COURSE COVERS
This course is comprehensive, covering the fundamentals of prototypes, composition and class-based languages.
Simple enough.
The only problem is that in order to truly understand JavaScript, you need to move beyond the basics. That’s why this course covers the basics, and more advanced concepts.
First, this course teaches you basics:
-
Learn what prototypes are
-
Learn why everything in JavaScript is considered to be an object
-
Learn how to set and get an object’s prototype
-
Learn how to create custom prototypes
-
Learn about the instantiation patterns in JavaScript
-
Understand class instantiation introduce by ECMAScript
-
Master the prototype chain
-
Learn about the __proto__ property
-
Lean about the function’s .prototype property
-
Understand why everything in JavaScript is considered to be an object
-
and a whole bunch more!
This course also teaches you the advanced concepts:
-
Learn why it’s not good practice to amend the prototype during runtime
-
Why you shouldn’t add everything to an object’s prototype
-
Learn the limitations of prototypes
-
Lean the modern ways to get and set an object’s prototype
-
Learn why __proto__ has been partly deprecate by ECMAScript
-
Understand why the [[Prototype]] is a hidden property
-
Learn why the “.prototype” property only matters for constructor functions
-
Practical example of setting up a prototype chain by using the new keyword, using Object.create() versus setPrototypeOf(), and comparing this to the new class syntax
-
Understand the differences between prototypal languages vs classical languages
-
Understand composition vs prototypes
And yes, we will code examples in a fun way, and look at how objects work under the hood.
## The most comprehensive JavaScript Prototype course on Udemy ##
Successful programmers know much more than memorizing a few lines of code. They also know the fundamentals of how a programming langauge works under the hood. Because the JavaScript creators decided to build JavaScript on prototypes, it becomes crucial to understand what prototypes are, how they work, when to use them and why they are so powerful.
