From a55a3f77a14f44c684c145f85e03aad25bd030f3 Mon Sep 17 00:00:00 2001 From: Spencer Handley Date: Tue, 28 Oct 2014 13:56:14 -0700 Subject: [PATCH] Added comma to increase readability. When thumbing through the docs, I noticed a few missing commas. I inserted two commas and did not alter any source code. --- docs/docs/03-interactivity-and-dynamic-uis.md | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/docs/03-interactivity-and-dynamic-uis.md b/docs/docs/03-interactivity-and-dynamic-uis.md index 5c437aedf06..3e11e2ddae8 100644 --- a/docs/docs/03-interactivity-and-dynamic-uis.md +++ b/docs/docs/03-interactivity-and-dynamic-uis.md @@ -45,9 +45,9 @@ If you'd like to use React on a touch device such as a phone or tablet, simply c ## Under the Hood: Autobinding and Event Delegation -Under the hood React does a few things to keep your code performant and easy to understand. +Under the hood, React does a few things to keep your code performant and easy to understand. -**Autobinding:** When creating callbacks in JavaScript you usually need to explicitly bind a method to its instance such that the value of `this` is correct.

With React, every method is automatically bound to its component instance. React caches the bound method such that it's extremely CPU and memory efficient. It's also less typing! **Event delegation:** React doesn't actually attach event handlers to the nodes themselves. When React starts up, it starts listening for all events at the top level using a single event listener. When a component is mounted or unmounted, the event handlers are simply added or removed from an internal mapping. When an event occurs, React knows how to dispatch it using this mapping. When there are no event handlers left in the mapping, React's event handlers are simple no-ops. To learn more about why this is fast, see [David Walsh's excellent blog post](http://davidwalsh.name/event-delegate).
