SKED

is a minimalistic tool to schedule functions' execution.

How to use it

1. Create an object where the key/value pair means delay of execution / callback function. Delay times are in milliseconds.
2. Pass that object as an argument to sked. This will return you a new function you can keep...
3. ...then initialize it to start the timeline.

For example:

var scheduledCallbacks = {
    "200": callbackFunctionOne,
    "700": callbackFunctionTwo
}

var timeline = sked( scheduledCallbacks )

timeline()

Tip: you can pass a whole sked timeline as a value in the schedule object. This allows you to manage complex timelines in easy chewable bites.

Installing

You can install "sked.mjs" as an ES6 module or link the script "sked.js".

What sked does

is to compute the optimal interval so all callbacks can be called at the right time. Then it creates a lightweight setInterval() wired to run each callback at the right time and to clear itself when finished. Sked returns to you a function with which you can start the animation whenever you like it.

Why was sked created?

To manage javascript animations. GreenSock is the powerhouse on JS animation, but I've come to realize KUTE.js has every tool I need, and with a MIT license I am less worried about adding it to projects.

But actually KUTE.js is missing one tool: the timeline, which allows me to polish when successive animations start. In particular, I wanted to start an animation some miliseconds before the previous has ended, which I cannot reproduce with KUTE.js' callback.

Sked is not as powerful as GreeSock's timeline, not by a long shot. But by feeding each animation timeline as a callback to a master timeline, I can easily manage complex animations, without which I'd still be tied to proprietary code.
