From Wikipedia
reactive programming is a programming paradigm oriented

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

A = 1B = 3C = A + B // C == 4
A = 2
ROME 27-28 march 2015 - Luigi Dell’Aquila
Propagation of change
