/**
|
|
* Simple helper function to sync a read-only dependency with writable state. This only syncs
|
|
* in one direction, from the dependency to the state. If you need to sync both directions, you
|
|
* should use the `box.with(() => dep, (v) => (dep = v))` pattern.
|
|
*
|
|
* @param getDep - A getter that returns the value that may change and whose new value will be
|
|
* passed to the `onChange` function passed as the second argument.
|
|
* @param onChange - A function that accepts a new value to react to or keep other state in sync
|
|
* with the dependency.
