The JavaScript programming language has officially reached its 30th year, counting from its announcement in 1995. What began as a modest project is now the "heart" that powers the vast majority of modern websites worldwide, as well as the foundation for countless server and desktop projects. Although it has become one of the indispensable core standards of web programming, few people know that behind this success lies a colorful development history, some amusing misunderstandings, and trademark disputes that remain unresolved to this day.
A lightning-fast birth and near-total dominance
Thirty years ago, two tech giants of the day, Netscape and Sun Microsystems, joined forces to introduce JavaScript as a new cross-platform scripting language, with the goal of building rich internet applications. The language's creator, Brendan Eich, built the technology in a programming marathon that lasted just 10 days while he was working at Netscape. It is hard to believe that a technology cooked up in a rush, in under two weeks, could become the solid foundation for the entire internet that followed.
Today, according to statistics, JavaScript is used by about 98.9% of all websites worldwide. That is a nearly absolute level of dominance. Looking back at the history, though, things could easily have gone in a very different direction without a few strategic decisions and some strokes of fate.
Brendan Eich originally designed JavaScript to bring a new level of interactivity to web pages, making them livelier instead of just boring static text. The language also had to be approachable for professional programmers and hobbyists alike. To achieve this, he drew inspiration from many sources, including the Scheme dialect of the Lisp language, the Self language, and several other technologies.
The "old wine in a new bottle" story and the confusion with Java
One of the most entertaining anecdotes in tech history is the name JavaScript itself. At the time, Sun Microsystems succeeded in tying JavaScript to Java, even though the two languages are worlds apart. As editor Benj Edwards wryly reminded us on Ars Technica, the only thing JavaScript and Java have in common is about what "car" and "carpet" have in common. They look alike on the surface, but their purpose and construction have nothing to do with each other.
In the 1990s, Sun Microsystems promoted Java as a powerful tool for building complex enterprise applications. JavaScript, meanwhile, was positioned as a companion to Java, handling smaller tasks on the client side. Thirty years on, Java applets have, fortunately, almost entirely vanished from the web platform because they were heavy and insecure. The "sidekick" JavaScript, by contrast, survived and thrived, and is now everywhere.
In fairness, though, Java remains among the top programming languages in the world today. Even if it is no longer the king of websites, Java is still the number one choice for enterprise software, backend services, and large-scale systems.
As for the name, Eich originally wanted to call his brainchild "Mocha." Netscape then renamed it "LiveScript" for a short time before settling on "JavaScript," the name we know today. The language was first announced in December 1995 and reached its official 1.0 release in March 1996. Netscape's engineers kept refining JavaScript over time, and the first generation of internet users got to experience its early features through the legendary Netscape Navigator browser.
Legacy, standardization, and the legal fight
Before Microsoft integrated Internet Explorer into Windows 9x in its push to dominate the web, Netscape's proprietary browser was the de facto standard for surfing the internet in the early days, on PCs running Pentium chips. Netscape and Navigator have long since faded into the past, but the legacy they left behind, JavaScript, still powers browsers, development platforms, and even the server-side software frameworks behind modern cloud applications.
Over time, JavaScript eventually became an industry standard through the ECMAScript specifications, with ECMA standing for the European Computer Manufacturers Association. This was an important turning point that gave the language the unity and stability to flourish as it does today.
Not everything has gone smoothly, however. The "JavaScript" trademark has been fueling long-running legal conflicts between Oracle and the broad community of JS developers. Oracle is said to have taken ownership of the JavaScript name after acquiring Sun Microsystems in 1997. Notably, even though it holds the name, Oracle has made no meaningful contribution to the language's development.
The JS developer community has long wanted to reclaim the freedom to use the name "JavaScript" legitimately, but Oracle has so far shown no intention of backing down or handing the rights over. Still, whatever it is called and whoever holds the trademark, no one can deny JavaScript's role as the backbone of the modern internet over the past 30 years.
