Wikipedia:
Bi-directional text is text containing text in both text directionalities,
both right-to-left (RTL) and left-to-right (LTR). It generally involves text
containing different types of alphabets, but may also refer to
boustrophedon, which is changing text directionality in each row.

Computed<T>
-
Data is often derived from other pieces of existing data. The
computed function lets you combine the values of multiple signals into a new signal that can be reacted to, or even used by additional computeds. When the signals accessed from within a computed callback change, the computed callback is re-executed and its new return value becomes the computed signal's value.

-
The idea for
connect comes from Anguar Signals with RxJS:

Effect
-
The
effect function is the last piece that makes everything reactive. When you access a signal inside its callback function, that signal and every dependency of said signal will be activated and subscribed to. In that regard it is very similar to computed(fn). By default all updates are lazy, so nothing will update until you access a signal inside effect.
