Lwd is a library that lets you build values that changes over time. It is a simple form of incremental computation, in the like of Incremental and React . It is only about interactivity. A bunch of companion libraries make it usable in different settings:

Sometimes people ask this question from a philosophical perspective, so I’ll start with a philosophy-style answer: does caffeine change you into a different person? Does alcohol? Does stress? Does depression? Does pregnancy? Does the birth control pill? Does falling in love? All of these change your brain chemistry, some of them in profound ways. Some of them change how you act, pretty noticeably. Does that mean you’re a different person? Read Derek Parfit for a good answer; my mediocre answer is something like “these things make you act differently but don’t make you feel a rupture in your sense of continuity with yourself.”
