Functional vs Object-Oriented Programming Paradigms

John Nweke — Wed, 31 Jan 2024 16:35:03 +0000

So, my CS Students keep asking me - what are the differences between Procedural and Object-oriented programming languages?

Makes sense that the info is all in one place now. OOP definitely built on the mistakes/faults of functional programming, and the inclusion of methods, encapsulation, and inheritance make OOP infinitely better.

Feature	Procedural (Functional) Programming	Object-Oriented Programming (OOP)
Focus	Procedures or routines (functions)	Objects (instances of classes)
Data and Functions	Separate entities	Bundled together in classes
Global Data	Yes, often used	Encourages encapsulation and local data
Modularity	Emphasizes breaking down into procedures	Emphasizes breaking down into objects and classes
Classes and Objects	Not applicable	Central to the paradigm, defining blueprints
Encapsulation	Limited	Key principle, bundling data and methods
Inheritance	Not typically supported	Supports the creation of derived classes
Polymorphism	Not typically supported	Supports polymorphism, method overloading, etc.
Example Languages	C, Pascal, Fortran	Java, C++, Python, Ruby, etc.
Abstraction	Less emphasis	Emphasizes abstraction for real-world modeling
Code Reusability	Achieved through functions	Achieved through inheritance, polymorphism, etc.
Complexity	May be suitable for simpler projects	Often preferred for larger, complex projects
Real-world Modeling	May not closely mirror entities	Designed to closely mirror real-world entities
Language Examples	C, Pascal, Fortran	Java, C++, Python, Ruby, etc.

What do you think? Were all the bases covered? Miss anything?

Visual Studio Code Settings for Newbie Coders

VS Code Settings for Newbie Coders

It's no secret that Visual Studio Code is the numero uno code editor for development today. A staggering percentage of programmers today use VS Code and swear by it - for good reason too! It has over 400 settings that can be adjusted to fit every user's needs, plus a bunch of extra stuff that it can do.

However, just because it has 400 settings doesn't mean you need to change ALL of them. Many times I have found myself going down the rabbit hole of getting busy doing nothing while I changed several settings on my code editor. Folks, it's not worth it. If you're learning Spanish, it's better to spend time learning and speaking rather than making nice little artsy cards that say 'Hola!'

I wrote up a short list of extensions for you to get set up and going immediately. If I missed one, let me know!

List of Visual Studio Code extensions for new programmers

1. One Dark Pro Monokai Darker

This is the color theme I use currently. The colors are nicer and richer. Comments are grayed out so the focus is on the code!

Other options: Atom One Dark , Sublime Material , Visual Studio Dark

2. Material Icon Theme

This changes the file icons on the side panels to easily identifiable icons - so you instantly know if you're in a HTML file, CSS file, or JS file.

3. Bracket Pair Colorizer

There's nothing more frustrating than spending 5 hours debugging your code only to realize you missed closing a bracket! Bracket Pair Colorizer helps you see visually how each bracket or curly brace is connected with its pair.\
Hint: VS Code automatically closes brackets and curly braces for you as well. Ain't that grand?

4. Code Runner

This allows you to run your code directly inside VS Code - and saves you the stress of going back and forth between several tabs of Google Chrome consoles. VSCode is now your terminal! You can choose what programming language you want to run, or set your default language to Javascript.\

5. ESLint and JSHint

They are two different extensions but they work well as a pair, allowing you to figure out what's wrong with your code. ESLint tells you if something is off in your Javascript code. JS Hint (like it's name) gives you hints on your Javascript (and also does some of ESLints functions). Pretty nice.

6. Beautify

This helps make your code readable and adds tabs (or spaces) where necessary so you can see how your code is nested.

7. Markdown Preview Enhanced

This lets you write articles (like this one) inside VS Code using Markdown Syntax and see what the finished product would look like.

8. Bootstrap 4, Font awesome 4, Font Awesome 5 Free & Pro snippets

Don't let the ridiculously long name fool you - this is a super helpful extension that allows you to insert Bootstrap 4 into your project with short cuts. If you will be using Bootstrap to prototype your ideas (which you should be doing), this will help you get that done in a fraction of the time.

That's it! If you are new to programming or to VS Code, these are the basics you need to get set up and running. Don't spend 3 weeks tweaking your code editor; go ahead and actually write some code. What do you think?

See you at the top,
John.
