Before anything like an Android device or iPhone existed, desktop computers were the battleground for the browser wars. The battle involved billions of dollars invested by a number of companies, all based on the premise that whoever ruled the desktop browser market would own the internet. Today, mobile devices account for nearly half of all website traffic. Back in the 1990s, however, almost all of the action on the web came from desktop machines, and the vast majority of those desktop machines were running some flavor of Microsoft Windows.
In the browser world, the first-mover advantage belonged to Netscape Communications Corporation. They built the Netscape Navigator browser that made the web accessible to millions for the first time. Netscape had more than 80% of the market, but they also had no shortage of competition. IBM had a browser for OS/2. Oracle had the Powerbrowser, a Netscape-compatible product that included something called the Database Markup Language. The real danger to Netscape, of course, came from the company that owned more than 80% of the world's desktops: Microsoft.
Strategically, Netscape realized that the web needed to move past static web pages to reach its full potential. Even if they were created dynamically by something like a CGI script on the web server, pages didn't change once they arrived in your browser. If you wanted to see even a slightly modified version of a page, you had to send a request back to the server and wait for a response. For all its sophistication, a web browser felt a lot like a dumb terminal attached to a mainframe. What web developers needed was a programming language that would run in the browser, taking advantage of the processing power of the desktop machine to give users a richer experience.
So in 1995, hearing footsteps from Redmond, Netscape decided to shoot for the moon and create that language. Netscape CEO Jim Clark had brought in a gifted programmer named Brendan Eich, who arrived with the idea of implementing the programming language Scheme in the browser. Scheme was adored in academia, but didn't have much traction in the marketplace. Eich thought it might be a good fit for programming web pages. He later referred to Scheme as "that beautiful research language I was tempted with."
Only there was a complication: Netscape had licensed Java from Sun Microsystems. A commonly held opinion was that Java should be the language of the browser. Unfortunately, Java was too heavy for the slow connections most people had in those days. Developers had to compile their code and then deliver that code to the browser. Good luck if your code needed a different version of Java than the one the user had on their machine. This meant they needed the patience to download a Java Virtual Machine that was 10 MB or more (!) across a connection too slow for many of today's users to comprehend. Back then, the web page and whatever non-Java content it contained were probably no more than a couple hundred KB; there was just too much overhead for Java to work.
In contrast, Eich, Netscape's Marc Andreessen, and Sun's Bill Joy all agreed that the world needed a BASIC-like language that would be a good fit for people who didn't know what a compiler was. Should anyone creating a web page have to understand what
public static void main(String args) means? Eich didn't think so.
On a personal note, a story from the International House of Hubris: in March of 1996, I was in San Francisco for the first Netscape Developers Conference. I don't remember the name of the young, Zegna-clad millionaire who said it, but he told the audience that you could write for Netscape Navigator...and if you wanted the other three percent of the web, you could target Internet Explorer. Much snickering ensued.
The following week, I stayed in San Francisco to attend the Microsoft Professional Developers Conference, the show where Bill Gates and company finally understood the internet. If you have some time to kill, watch Gates' keynote. Seriously. It changed the world we live in. The keynote included demos of games, virtual reality, and state-of-the-art web design, all of which look hilarious now. There was also a demo that ended with the Blue Screen of Death in front of thousands of people; however, that doesn't seem to be in the archives. (No judgment, we're all programmers, we've all been there. Although maybe not in front of thousands of people while our boss, a.k.a. the richest man in the history of money, looked on.)
At the show, Microsoft announced a full-out pivot to make everything in their product line internet-enabled in one way or another. This was an escalation of their ongoing attacks on Netscape's business model. In late 1996, Netscape Navigator still had 80% of the market and a list price of $49. (Yes, you had to pay money to get a browser. Talk to your grandparents about what it was like back then. Also, ask them about something called "dialup.") Not only was Windows going to contain a free web browser, but Microsoft was giving away a web server as well. Unfortunately, it turned out Internet Explorer wasn't quite compatible with Netscape and other browsers to come, creating a thorn in the side of every web developer on Earth for the next 15 years or more.
At any rate, I left San Francisco convinced that Netscape had no idea what was about to hit them. I was also convinced that Virtual Bubble Wrap, a Flash-based game that ran in Netscape Navigator, was the greatest use of the Internet ever. I believe I was right on both counts.
The little language that could
Then, the rise of the Node Package Manager (npm) to manage dependencies meant a very small application could leverage other packages to do really sophisticated things. As a self-serving example, the knative-proxy package in the Coderland Compile Driver needs fewer than 40 lines of code to handle the HTTP POST and OPTIONS verbs. And it took yr author maybe 30 minutes to write.
