In 1980 , BYTE Magazine dedicated an entire issue to the FORTH programming language. It is arguably the simplest and smallest language ever developed, but its postfix notation and alienation with disk operating systems made FORTH fade into the dusty shelves of history.
Today, FORTH has some uses at NASA, but is otherwise only a teaching tool for how a programming language can be built with extremely little CPU resources.
Internet of Things (IoT) are pushing the limits in the small. There are now $1 microcontrollers with WiFi built-in, that has not more memory than a computer from 1980. Of course C is used to program such devices, but FORTH not only allows for as small as, or even smaller, codebase but it gives you a REPL environment, to quickly explore the microcontroller and get rid of compile cycles.
We will look closer at FORTH, and a small IoT application will be demoed as well.
