low: flow method

[betula]

// v: signal|value|ready|etc...

v.flow((dest, val, prev?) => val >= 0 && dest(val)); // That case is new one.

// That necessary for creating a new entity (signal, value, ready, etc...), from another entity

[betula]

const v = value(0);
const positive_v = v.flow((positive, n) => n >= 0 && positive(n));

on(positive_v, console.log) // only positive reactions and values

Question: How to make a signal from value?

const s = signal.from(value); // That syntax is perfect!

[betula]

Add possibility for use flow with another reactive value

const src = value(0);
const dst = value(0);

src.flow(dst);

flow.filter added 3eb5a8f

Extend syntax for flow.filter

class SwipeAnim {

  get process() { return swipeAnimProcess.val; }
  set process(v: boolean) { swipeAnimProcess(v); }


  constructor() {
    swipeBreak.flow.filter(() => this.process);
    // or new syntax
    swipeBreak.flow.filter(swipeAnimProcess);
  }
}

Extend syntax for flow.filter

export const allReady = ready.from(
  signal.combine(backReady, frontReady)
    .view(([back, front]) => back && front)
    .flow.filter((f) => f) // to -->     .flow.filter()
);
