The JavaScript World Domination
There were essentially two (more-or-less) well-known laws in the IT community that contributed to (predicted, even) JavaScript’s world domination.
Moore’s Law has been generalized in several ways, how it is really about "exponential progress, in the wake of tiny revolutions and paradigm shifts"
Atwood’s Law by Jeff Atwood: "Any application that can be written in JavaScript, will eventually be written in JavaScript."
Great overview of the history, present and future of JavaScript in the browser, on the server, the desktop and IoT devices.
