From Wikipedia

reactive programming is a programming paradigm oriented

around data flows and the propagation of change

ROME 27-28 march 2015 - Luigi Dell’Aquila

Propagation of change

A = 1B = 3C = A + B // C == 4

ROME 27-28 march 2015 - Luigi Dell’Aquila

Propagation of change

A = 1B = 3C = A + B // C == 4

A = 2

ROME 27-28 march 2015 - Luigi Dell’Aquila

Propagation of change

A = 1B = 3C = A + B // C == 4

A = 2

C == ?
