3. What is the difference between classical inheritance and prototypal inheritance?
Class Inheritance: instances inherit from classes (like a blueprint — a description of the class), and create sub-class relationships: hierarchical class taxonomies. Instances are typically instantiated via constructor functions with the
Prototypal Inheritance: instances inherit directly from other objects. Instances are typically instantiated via factory functions or
In JavaScript, prototypal inheritance is simpler &
more flexible than class inheritance.
Good to hear:
🔹 Classes: create tight coupling or hierarchies/taxonomies.
🔹 Prototypes: mentions of concatenative inheritance, prototype delegation, functional inheritance, object composition.
Red Flags:
🔻 No preference for prototypal inheritance & composition over class inheritance.

Class Inheritance: instances inherit from classes (like a blueprint — a description of the class), and create sub-class relationships: hierarchical class taxonomies. Instances are typically instantiated via constructor functions with the
new keyword. Class inheritance may or may not use the class keyword from ES6.Prototypal Inheritance: instances inherit directly from other objects. Instances are typically instantiated via factory functions or
Object.create(). Instances may be composed from many different objects, allowing for easy selective inheritance.In JavaScript, prototypal inheritance is simpler &
more flexible than class inheritance.

4. When is classical inheritance an appropriate choice?
The answer is never, or almost never. Certainly never more than one level. Multi-level class hierarchies are an anti-pattern. I’ve been issuing this challenge for years, and the only answers I’ve ever heard fall into one of several common misconceptions. More frequently, the challenge is met with silence.
“If a feature is sometimes useful
and sometimes dangerous
and if there is a better option
then always use the better option.”
~ Douglas Crockford
Good to hear:
🔹 Rarely, almost never, or never.
🔹 A single level is sometimes OK, from a framework base-class such as React.Component.
🔹 Favor object composition over class inheritance.

5. When is prototypal inheritance an appropriate choice?
There is more than one type of prototypal inheritance:
- Delegation (i.e., the prototype chain).
- Concatenative (i.e. mixins,
- Functional (Not to be confused with functional programming. A function used to create a closure for private state/encapsulation).
Each type of prototypal inheritance has its own set of use-cases, but all of them are equally useful in their ability to enable composition, which creates has-a or uses-a or can-do relationships as opposed to the is-a relationship created with class inheritance.
Good to hear:
🔹 In situations where modules or functional programming don’t provide an obvious solution.
🔹 When you need to compose objects from multiple sources.
🔹 Any time you need inheritance.
Red flags:
🔻 No knowledge of when to use prototypes.
🔻 No awareness of mixins or

How to check an image for deepfake
Many users use AI-generated faces in their avatars. To detect a fake profile image, the Fake Profile Detector extension appeared.
With the help of a neural network, it determines whether the person in the photo is artificially generated or real.
All you need to do:
✔️Install the extension in Google Chrome and give permission to send notifications.
✔️Open the picture or avatar you want to scan in your browser.
✔️Right-click on it and select Check Fake Profile Picture. You'll quickly get a notification with the results - what's the percentage probability that the face is generated.
Use it!

⭐️6 Tips to Study Coding Effectively⭐️
by UFV Academic Success Centre
1. Don’t just read the code example—Type it out and then create a similar one
🔹 A code sample is the representation of the idea or program.
🔹 Type it in your own words to understand how the five components are working together.
🔹 Create a similar sample to understand the abstract of the program.
🔹 Try some code challenges from some well-known websites, such as leetcode, codewars, and
topcoders.
2. Practice and keep track of what you have learned
🔹 Practice makes perfect.
🔹 As a programmer, you often can have some repetitive tasks. Keeping track of what you learn will
help you quickly refer back to the tasks you have done.
🔹 Document what you have learned. Documentation is a good resource to help you look up the
algorithm/solution and repetitive tasks easily and increase your productivity rapidly.
3. Try to create, then build your own program
🔹 Apply what you have learned to a real-life example.
🔹 Building your own program brings you to the next level of program abstract and will help you feel
satisfied and accomplished with what you have learned.
🔹 When you come up with a solution, try a different approach. There is more than one right way to
do something, and searching for different solutions will help you develop your problem solving
skills.
4. Learn how to research and solve problems
🔹 Search for topics by specific keywords.
🔹 Learn how to research your problem when you get stuck. Some websites may help, such as
stackoverflow, stackexchange, github, and forums.
🔹 If you find a solution online, make sure you understand every line of code. You will learn more this
way rather than just copying and pasting it into your project.
5. Take a break while debugging
🔹 Consider taking break to clear your mind when you encounter difficult bug.
🔹 Stepping away for a few hours will allow you to return with a fresh perspective.
6. Things to avoid
🔹 Perfection: As a beginner, improving your coding skills and problem solving are more important
than making your code perfect. Seeking perfection will cause you to procrastinate instead of
progress. Remember that mistakes are opportunities to learn.
🔹 Comparison: Never compare your code style/knowledge with anyone else. You will end up being
disappointed and demotivated. Practice and trust yourself.
🔹 Complexity: Learn how to break a problem into smaller problems, so you can conquer it more
easily.
A good programmer is able to make a program simpler and less complex. Make it work first, then
make it right, finally make it fast. “Simplicity is the ultimate sophistication,” said Leonardo Da Vinci.
