# A brief history of programming

The earliest computers were programmed using punched cards to represent a
**binary number system**, the number system that computers use. The binary
system is made up entirely of $1$s and $0$s that loosely translate to “on” and “off.”
On the cards, a hole represented $1$ and no hole $0$ . After this, people started
to develop languages that could be used to “speak” to the computer.

The first computer programs were written in **machine code** and **assembly
language.** These are **low-level programming** languages that are closely
associated with a computer’s hardware. This means they can be difficult
languages to program in because they involve writing abstract code that’s
heavily tied to a computer’s architecture. In fact, it’s rare to find anyone who
programs in machine code or assembly nowadays, but those who do will work
closely with a computer’s hardware—for example, writing device drivers or
working on embedded systems.

**High-level programming** languages use abstractions that make the code easier for humans to read and write. Programs are written in a language, such
as Swift, C# or Java, which is then compiled into machine code and executed.
The programs written using these languages are very fast, making high-level
languages suited to writing games and professional business software where
speed is important.


**Scripting languages** are another type of high-level language, but they’re
**interpreted** instead of **compiled**, which means that they’re translated into
machine code when the program runs, rather than beforehand. This means
that they’re often slower than compiled languages, although interpreters are
becoming more sophisticated, making some interpreted languages almost as
fast as compiled languages. Some common scripting languages that you
might hear about are Python, Ruby and, of course, JavaScript.

# JavaScript
The language we’ll be learning in this book is JavaScript, often referred to as
the language of the Web. Pretty much every web browser can run JavaScript,
making it one of the most popular programming languages in the world.
