I started with Elixir just a couple weeks after the switch from 1.4 to 1.5, so the bulk of online resources were out of date (or at least resulted in deprecation warnings). This guide is for defining Elixir 1.5 supervised modules.
It's not actually terribly complicated. It's just sometimes unclear from examples what's implemented by the language and what you actually have to implement yourself.
Say we want a supervision tree like this (where each atom is a process):
:a
/ \
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.
elem.offsetLeft,elem.offsetTop,elem.offsetWidth,elem.offsetHeight,elem.offsetParent
