The basic task of change detection is to take the internal state of a program and make it somehow visible to the user interface. This state can be any kind of objects, arrays, primitives, … just any kind of JavaScript data structures.

No compiler was found at C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.8\tsc.exe.
