Software and computer code are extremely prominent in today’s high tech world. Believe it or not, you interact with code every single day, sometimes without even realizing it. Most devices in your home including your phone, TV, and even your fridge rely on code to function correctly.
Coding (or computer programming) is the process of writing instructions for computers. In order for devices to perform useful tasks, they must be told exactly what to do. From simple tasks like a microwave timer or a car parking sensor to more complex tasks like rendering 3D graphics and physics for video games, our world is built on code.
For many reasons, the world needs talented coders. If you're ready to learn to code and get into a stable industry, we're here to share the skills you need to learn and the courses that will get you there.
What Exactly Does a Coder Do?
Coders and programmers do more than just write lines of code. They are responsible for the following:
- Understand the software requirements: Every application is designed to make our life easier or perform a useful task. The coder must have a clear understanding of the problem they are trying to solve.
- Create a solution: Before writing any code, it’s good practice to have a plan in place. The solution can be drafted out in pseudocode ready for programming. Pseudocode is a simplified form of computer code, designed to be read by humans, not computers.
- Write the code: The coder will spend most of their time actually writing and testing computer code. Objects, classes, functions, statements, variables, and operators are used to instruct the computer to solve a specific problem.
- Maintain the code: Once the application is finished, bugs may be discovered or new features requested. The coder must update old code as requirements change over time.
Common Coding Terms
As a coder, you'll frequently come across the terms listed below:
- Algorithm: A mathematical equation or a set of instructions that are followed to solve a calculation or perform a useful task.
- Binary: A way of representing data using just two options.
- Code: A command or set of instructions for the computer.
- Bug: An error that slows or stops the program from working.
- Debug: The process of finding errors and fixing them.
- IP address: A string of numbers that are assigned to an Internet user.
- Decompose: Break a problem down into more manageable pieces.
This list is not exhaustive and there are other concepts that you need to master. For example block-based programming, object-oriented programming, data handling, and memory management are all specialized aspects of computer programming that you'll become familiar with.
Let’s explore 8 highly recommended courses for aspiring coders:
The course outlines key principles to keep in mind while coding in Java. The code should be simple, object-oriented, and secure. It should be threaded, interpreted, and dynamic.
3. SQL for Data Science: In this Coursera course, you’ll learn to saturate and analyze data effectively. By the end of this course, you’ll be able to handle data numbers and strings, deal with complex data, and understand SQL fundamentals.
You’ll gain insights into filtering, calculating, and modifying data with SQL and SQLite.
CSS (Cascading Style Sheets) is another front-end technology that helps coders design and style web content.
In this course from Johns Hopkins University, you’ll learn to build web pages using HTML and CSS. These programming languages are ideal for beginners. You will get familiar with Ajax (which is a method of building interactive applications) as well.
5. Data Science Bootcamp: In Thinkful’s online Data Science course, you’ll learn some of the most valuable programming languages for data scientists, like Python and R.
Ideal for beginners, Python is designed to be easily readable with uncluttered formatting. It frequently uses English keywords, whereas other programming languages use symbols or punctuation marks like curly brackets. This course is heavily focused on using Python for data analysis.
R is a programming language and development environment for data analysis and graphics. This language is mostly used by statisticians and data miners for data analysis. It includes linear and non-linear data modeling, clustering, and classification. Like Python, R is also an interpreted language, which means that the code you write is interpreted into a language understood by the computer.
6. Ruby on Rails - An Introduction: Commonly known as Rails, Ruby on Rails is a server-side web application framework written in Ruby.
The Rail framework is geared for rapid prototyping. In this course from Johns Hopkins University, you’ll explore how to build web applications using the Ruby on Rails framework. This course will also introduce you to more advanced topics such as arrays, hashes, unit testing, Heroku, and Sublime Text.
7. Functional Programming in Scala (Specialization): Functional programming (also known as FP) is the process of building software by composing and applying certain mathematical functions. Lisp, Python, and Clojure are examples of functional programming languages.
This course offered by EPFL allows you to write functional code to manipulate data. You’ll learn Big Data analysis with Scala, Spark, Apache Spark.
8. Introduction to Programming in C: C is a low-level language that is great for coding algorithms and solving complex problems with limited resources.
This course from Duke University will include programming fundamentals, pointers, arrays, and recursion. You’ll also be introduced to compiling, debugging and memory management techniques.
