Tip

For convenience, you can open this playground in a separate tab by clicking on this icon , detach that tab as a separate window, and watch the video in one window and play with the code in the playground in another.

Key ideas

UI side effects can be connected with state callbacks to:

• single Validation states;
• group states;
• and also Predicate states.

Effect function can have:

• different effect values to be applied for each validity state;
• different delays to be applied for each validity state;
• the target (event target by default) to which the effect is applied and which can be overriden;
• a delay which can be cancelled by a later applied effect with the same effect ID.
