Why learn Computer Science before learning to code?
The truth is: Computer Science isn’t sexy.
If you want to learn how to code as quickly as possible, understanding what happens inside your computer might sound too technical and even boring. You just want to get started with your first online coding course and create something awesome asap!
And hey, that’s perfectly normal. I felt the same way when I first started to teach myself to code.
But here’s the deal:
Understanding Computer Science fundamentals will help you become a better developer in the future.
Think of it like this:
- Coding is all about making computer do what you want.
- Computer Science basics help you know what your computer is capable of.
- When you know how computers work, you can write better code and more efficient programs.
And you don’t have to dive too deep into the world of computer science. You simply want to understand the basics so you have a good idea of what’s happening inside a computer when your programs are running.
If you’re still on the fence, let me walk you through a few good reasons to take time to learn Computer Science fundamentals when you are new to tech.
Reason #1: You will become better at solving problems
At its core, Computer Science is all about understanding what computers can do for us. No computer on this planet is all-mighty – the hardware inside always has its limitations.
Therefore, your programs should take those limitations into consideration.
You want to write efficient code that executes fast, so you need to design your programs to be easy on the scarce resources of a computer. This will help you become better at solving problems.

Reason #2: You will learn how to code faster
When you start learning how to code, you’ll come across more than enough technical terminology. Every new coding lesson will be packed with cryptic jargon you’ve never heard before.
That’s when the road can get a bit rocky. You start feeling confused and even overwhelmed, trying to figure out what that terminology means.
Here’s the good news: Learning Computer Science fundamentals will familiarize you with most of that terminology. And when you learn it separate from coding itself, you’ll see better progress. Even though it takes some time to learn CS basics before coding, your efforts will pay off, trust me.

Reason #3: You will write better code
And with “better” I mean more efficient. After all, we all like our computers to run smoothly without any unnecessary waiting around.
But although your smartphone has way more processing power than a computer just a few years ago, your programs still need to be efficient.
Again, understanding Computer Science fundamentals will help you on this. You’ll learn how to make the most of the limited resources of any computer out there. You can optimize your code and make sure it doesn’t use any more resources than necessary.
Can you teach yourself Computer Science online?
Computer Science online courses are obviously much more affordable than the tuition fees for a 4-year degree. But they’re also more hands-on, meaning you’ll apply what you’ve learned to real-life projects from the get-go.
Even though you can’t go into as much detail as with a college degree, you can still learn everything you need to know to become a better programmer.
Of course, I’d be lying if I told you that online courses could replace an entire college degree. They are two entirely different things.
But if you want to learn how to code to become a full-time developer or start freelancing to make money from coding, using online resources is perfectly OK.
The best online Computer Science courses for beginners
All in all, online courses are the best way to learn coding and Computer Science from scratch.
But most beginners feel overwhelmed by the plethora of resources available online. With hundreds to choose from, how can you find the best online Computer Science courses when you’re just starting out?
I know you don’t want to waste your valuable time or money on the wrong resources. Therefore, I’ve put together a small list of beginner-level courses for learning Computer Science fundamentals for you.
I’ve tested and hand-picked them all to help you find the best Computer Science online course to learn more about coding and tech faster. Let’s jump right in!
