This is one of those languages that appears to be under Microsoft's "Extend, Embrace and Extinguish."

TypeScript is noted also at https://en.wikipedia.org/wiki/TypeScript which appears to be very much like JavaScript. Since it is transcompiling to JavaScript you would not search for app or applets in TypeScript but JavaScript then port as need be. If nothing is found then you write it yourself.
