This simple programming language with built-in graphical functions and an easy to use and offline usable browser IDE is well suited as a teaching and learning language. You can also use it to write graphical applications that you can embed in a web page.
A URL can be created, that can start a code runner with the program encoded in a URL parameter.
Inside the code runner our program can be stored and run offline. The code runner is a PWA
(Progressive Web App). Therefore it works like a native app on the mobile device.
Easylang is statically typed and has as data types only strings and numbers (floating point), arrays of strings and numbers, and arrays of arrays. Arrays are 1-based and can grow.
