Uber::Option implements the pattern of taking an option, such as a proc, instance method name, or static value, and evaluate it at runtime without knowing the option's implementation.

The Track() function will snap the output to the next task that is “magnetic to” the track’s semantic.

Record filters allow you to require an instance of a particular class (or one of its subclasses) or a value that can be used to locate an instance of the object. If the value does not match, it will call find on the class of the record. This is particularly useful when working with ActiveRecord objects.

The CardLayout creates a store in context and the Card creates a standardized div container and registers it to the store so that the CardLayout has access to that DOM element. Then in afterUpdate you can move the DOM elements into columns and Svelte will not try to put them back where they go. It's a bit messy but it works.

I think that maybe instead of using the prefixed $$ globals, a more "natural" solution could look something like this: import { slots, props, parent } from '@component';

To explain further what exactly I’m building, the animated background is a pure code equivalent to the old music video, but runs as long as the full length of the album, though without any event triggers to tie it to the music (the animation runs continuously for the full amount of time that the uninterrupted album lasts, but does not pause or jump to a different location in the animation). It’s also extremely slow animation

With this change, we can re-run preload when the session store changes, e.g. as a result of something like this in a nav bar:

Say I have a separate API server that provides content for a Sapper route. I could just query that API in my route's preload function, but if the content changes rarely, I don't want to incur that cost for every page load and would much rather cache responses from the API on the Sapper side.

With the caveat that hero worship can be gross, distorting, and unhelpful to everyone involved, Svelte author Rich Harris (@rich_harris on Twitter) is one of my favorite open source developers. In the JS community he’s well-known among tool authors for spreading interesting ideas. He’s the creator of many open source projects including Rollup, the bundler of choice for many libraries including React and Vue.

The @const indicates that the value is read-only (i.e. it cannot be assigned to or mutated in an expression such as an event handler), and communicates, through its similarity to const in JavaScript, that it only applies to the current scope (i.e. the current block or element).
