Computer programs are often described as “sets of instructions,” and computer languages are thought of by many as merely the syntax and vocabulary for providing these instructions.
From this point of view, different programming languages may have varying grammar or vocabulary. Each may treat semicolons a particular way or require capitalization — but they are somewhat similar underneath. The reality of programming is much more complicated.
- In the last few decades, creating new programming languages has focused mainly on developer experience. Some languages solve programming problems.
- There are dozens of programming languages; we will go over 100 of the most common ones.
- Numerous programming tools and libraries exist, from ADO.NET to Git and Simple Object Access Protocol (SOAP).
- The history of programming dates back to 1804 when the Jacquard loom, which uses punch cards, was invented.
What Is Programming Today?
Most of the really “big” ideas in computer programming were developed in the 1950s and 60s. Many new languages have developed since then, but none represent a truly novel approach to logic and computation.
Creating new programming languages in the last few decades has focused much on developer experience. This may mean trying to enable code that is easier to write (the driving force behind Ruby) or easier to read (Python) or making certain types of logical structures and modes of problem-solving more intuitive.
Since theories and practices around language design have mostly settled into a widely recognized orthodoxy, much of the new and interesting work in developing programming practice centers around system architecture.
Relatively recent developments include concepts like Service Oriented Architecture (SOA) and Model-View-Controller (MVC), and frameworks like Ruby on Rails that enable programmers to work within these paradigms easily.
What Are Some Popular Coding Languages?
Here is a growing list of popular programming languages, markups, and protocols.
Advanced Business Application Programming, or ABAP, is one of the two languages used to create SAP applications. SAP is one of the biggest enterprise resource planning systems in use, and is important in the business community.
ActionScript is the programming language used to create Adobe Flash applications. Although Flash may be less important than it once was because of HTML5, it is still an exciting development system for creating graphics, animations, and games.
Ada is a programming language developed for the U.S. Department of Defense for creating mission-critical applications. Although it isn’t widely used, it is the language of choice when safety is seriously important, like in air traffic control applications.
ALGOL was one of the earliest high-level languages. But unlike Fortran and COBOL, it isn’t used much. Still, it is an important model for languages that came later.
Alice is a visual programming language to teach students basic computer science concepts. It uses 3D objects and a point-and-click interface to provide an easy way for students to get started with traditional programming.
APL is short for A Programming Language, and it is indeed that. Although it was created in the early 1960s, it is still in use because of its power, though it is a strange language.
ASP / ASP.NET
ASP is short for Active Server Pages. It was the first server-side scripting language for Microsoft’s IIS web server. ASP was replaced by ASP.NET, an open-source server-side framework.
Assembly language is the most fundamental kind of software development where the coder has complete access to the CPU. Whether used directly or as a way to better understand computers at the hardware level, it is a powerful skill to have.
Awk is an enormously powerful text-processing programming language that allows you to extract the data that you need from a file or other source and output it in any format you want. It is an old tool, but still as useful as ever.
It might seem hard to believe but in the early 1980s, the television broadcaster BBC had a computer and programming language developed simply for producing a successful educational series, The Computer Programme. Now it’s an amazing bit of computer history, but you can still get and use the language.
If you include its two derivatives, no language has had more use and impact than C. It is especially important for the development of Operating Systems and other foundational software. Many compilers and interpreters for other languages are written in C.
Originally “C with Classes,” C++ is, in many ways, simply a more advanced successor to C (though the situation is a lot more complicated). C++ was developed to add high-level programming paradigms to C while retaining the low-level hardware-manipulation capabilities. Many of these additions have been added to C over the years, and the languages are more like two dialects of a single language.
Used as the primary language for .NET programming, and much like C++, it is an extension of the C programming language, with the major addition being object-oriented capabilities.
COBOL is one of the oldest high-level programming languages that many people think is dead. But it is still in use throughout business and government doing mission-critical tasks. And that code still needs to be maintained and expanded. It offers an unusual opportunity for young software developers.
Cascading Style Sheets
Cascading Style Sheets (CSS) allow you to change the look of web pages. It’s usually the first thing you learn after HTML. CSS isn’t a traditional language, but it is an incredibly useful one.
Just as the C programming language came about because of deficiencies in the B programming language, D was designed to fix C. In particular, D makes C object-oriented. But unlike C++, which did the same thing, D is not backward compatible, and so doesn’t contain some of the weaknesses of C++.
Delphi is an object-oriented version of the Pascal programming language. It’s been around for over 20 years and is more popular than ever.
Dreamweaver is a powerful website-building tool that allows the user to create visually without losing complete control of hand coding.

Learn some tips and tricks.
IDL, or Interactive Data Language, is a computer programming language used primarily for data analysis and visualization. It is still widely used in aerospace and astronomy.
INTERCAL is a parody computer language designed in the early 1970s. It was meant to make fun of the tendency for programming languages to be overly technical and difficult to understand. But it’s still a real language you can download and maybe even get to do things for you. This assumes you are nice enough — but not too nice because INTERCAL doesn’t like that either.
Java is a high-level language designed to be used by the Java Virtual Machine. It has few external dependencies and was intended to run on any physical machine. It is used extensively in network architecture and embedded devices, kiosks, and other in situ computing applications. See our detailed hosting guide to Java.

OCaml is an object-oriented functional computer language. In the tradition of ML, it is used a great deal for writing other programming languages and development frameworks.
Pascal is a language much loved by programming purists. But that doesn’t mean it hasn’t kept up with the times and isn’t still used.
This is a useful tool for almost any programmer. As an interpreted language it does not need to be compiled, and is sometimes referred to as the “Swiss Army knife” of scripting languages.
PHP is the most popular server-side language on the internet. It is incredibly powerful yet easy to learn. Get started today: PHP Introduction.

What Should You Know About Programming History?
Computer programming is, at heart, mechanical. The great challenge for early computing was figuring out how to mechanize logic and mathematical computation. Technological advancement — inventing new components and miniaturizing them — came much later. The first computer — Charles Babbage’s difference engine — was made out of gears, and powered by a hand crank.
But the difference engine could only solve one kind of problem. To generalize the usefulness of this mechanical calculator, it needed to accept two kinds of input — data and programming. Babbage’s theoretical new machine, the Inference Engine, solved that problem.
Though the Inference Engine was never built in his lifetime, the very first computer program was written to be run on it. Ada Lovelace, a countess and hobbyist mathematician, wrote programs for Babbage’s computation device.
In the 20th century, programming became a well-developed science — a branch of theoretical mathematics. This led to the development of modern programming languages.
There were several competing ideas about the nature of computer programming and how languages should be structured. The “winner” turned out to be a set of ideas promoted by John von Neumann — ideas that included logical control structures like IF and LOOP.
This so-called “von Neumann architecture” allowed for the advent of programming as we know it, and the development of high-level computer languages. It has dominated the logic and structure of every major programming language since. Only a handful of non-von-Neumann languages (such Plankalkül) exist, and none have gotten any widespread use.
The Jacquard loom, which uses punch cards to store weaving designs, is invented. The idea of storing data on punched paper cards would later influence computer design. The first computers were programmed with punch cards, which continued to be used in some types of computing into the 1980s.
Ada Lovelace develops an algorithm for Charles Babbage’s Analytical Engine. The algorithm computed Bernoulli numbers, making Ada the world’s first computer programmer.
The Atanasoff-Berry Computer (ABC) was first tested. It was conceived in 1937 and then built by Iowa State University professor John Vincent Atanasoff and then graduate student Clifford Berry. It was arguably the first electronic digital computer. As with other early computers, it had many limitations. In particular, it could not be programmed.
The ENIAC computer was developed by the U.S. Government. It could only be programmed by presetting switches and rewiring the system.
Plankalkul, a language designed for engineering mathematical work, is developed by Konrad Zuse.
John von Neumann, working at the Institute for Advanced Study, conceived of two ideas that changed the course of computer programming. The first concept was that simple hardware should be controlled by complex instructions — that the “program” should be changeable without altering the hardware. The other idea was that computer programs should be broken down into small bits of conditionally executed code that could be jumped to from anywhere in the program. This allowed IF, ELSE, and LOOP structures to be written into computer programs.
Short Code, the first programming language, was developed based on von Neumann’s ideas. Unfortunately, it had to be “hand-compiled” — someone had to translate the program in binary (1s and 0s) by hand.
Grace Murray Hopper, working for Remington Rand, begins the development of a compiler for Shortcode that automatically translates (“compiles”) code into binary.
Autocode, an early compiler, is developed by Alick Glennie. He works on it in his spare time while attending the University of Manchester.

The future of programming
It’s hard to say where programming is going. In the short-term, we can probably expect more acceleration of the trends we’re already experiencing:
- Big data
- “Internet of Things”
But long-term, it is notoriously difficult to make accurate predictions. Quantum computing may lead to a whole new paradigm of computer programming. Computers may learn to program themselves, leading to the singularity and the end of the human era. We may discover how to use programming to mimic biological intelligence, leading to transhumanism. Or we might just figure out how to make our phones smaller.
Whatever the future holds, it is clear that programming — being able to read and write code in a handful of common languages — is becoming the new business literacy. Familiarity with programming concepts and the logic of computer systems and architecture is quickly becoming as important as basic business skills like sales, marketing, and design.
