Coding, or computer programming, is the process of designing and writing instructions for computers to follow. These instructions, or code, can be used to create a wide range of applications, from simple websites to complex software programs and video games. But where did coding originate, and how did it become such a vital part of our modern world?

The roots of coding can be traced back to the early 1800s, when mathematician Ada Lovelace worked on Charles Babbage’s analytical engine, an early design for a mechanical computer. Lovelace recognized the potential of the machine to do more than simple arithmetic, and she wrote what is now considered to be the first computer program, a set of instructions for the analytical engine to calculate Bernoulli numbers.

Fast forward to the mid-20th century, when computers began to be built with electronic components rather than mechanical ones. The first modern electronic computer, the ENIAC, was completed in 1945. At this time, programming was a tedious and time-consuming process. Programmers had to physically connect wires and switches to create the instructions that the computer would follow.

In the 1950s and 1960s, programming languages were developed that made coding more accessible and efficient. FORTRAN, the first high-level programming language, was created in 1957 to make scientific and engineering calculations easier to program. COBOL, a language designed for business applications, was developed in 1959. And in 1964, BASIC was created, making it easier for non-experts to learn to program.

With the advent of personal computers in the 1970s and 1980s, programming became even more accessible to the general public. Computer kits such as the Altair 8800 and the Apple I were sold as do-it-yourself projects that required users to assemble and program their own machines.

Today, coding is an essential skill for anyone who wants to work in fields such as software development, web development, data analysis, and artificial intelligence. Thanks to advances in technology and the development of programming languages and tools, coding has become easier and more accessible than ever before. And as our world becomes increasingly digital, the demand for skilled coders is only likely to grow.

Here is a table of the most commonly used programming languages as of 2021:
