Coding is the process of transforming computer instructions into a form a computer can understand. Programs are written in a particular language which provides structure and meaning to the programmer’s instructions. The programming code is written in and read from text files. A program, also known as source code, is a set of text instructions that tell a computer what to do.
When we talk about coding, we are usually talking about one of two things: writing code or reading code. When you write code, you use a text editor to create or edit files containing your source code. When you read code, you use a programming language to turn those text files into something that can be executed by your computer.
The most important thing to remember when learning how to code is that coding is all about communication. At its core, coding is simply telling a computer what you want it to do in a language it can understand. In order for your coded instructions to be effective, they must be clear and concise so that the machine can carry out your commands accurately.
