- Code is a set of instructions (or rules) that computers can understand; it might be helpful to think of code as a recipe.
- People write code, code powers computers and computers power many everyday objects like phones, watches, microwaves and cars.
- In fact, almost anything powered by electricity uses code.
- There are many names for people who code: coders, programmers, developers, computer scientists, software engineers, etc.
- Computers run on binary code—written in 1s and 0s—which is very difficult for humans to work with.
- But just as people can understand different languages computers can understand different languages (like Python, C, C++, Perl, Visual Basic, Java, Javascript, Ruby and PHP, among others) which translate our instructions into binary.
- There are “low-level” and “high-level” coding languages. Lower-level languages more closely resemble binary code while higher-level languages are easier to code in.
- So learning to code is literally like learning a new language (learning to construct sentences, etc.).
- Most popular programming languages in use today are high-level languages.
- C is a low-level programming language that is good for graphics-heavy applications, like games.
- Javascript is for for the web.
- Perl is sometimes known as the “Swiss-Army knife” of programming languages because of it’s multi-functionality.
- Many coding languages share similar basic features.
- A text file written in a particular programming language is called a program (think a set of instructions).
- There are many ways to learn how to code for free or very cheap.
