DOM Element recycling will be removed in Preact 8.
This should have no effect on most applications. In fact, it fixes a number of known issues related to element state not being fully reset on reuse.
💡 Why? Many DOM properties are stateful, and trying to reset them all when recycling is a game of whack-a-mole. Preact's size makes it infeasible to use whitelists to address these issues, so recycling is being dropped. >
| # SETUP: install documentation.js: | |
| npm i -g documentation browser-pipe | |
| # SETUP: install gist cli (github.com/defunkt/gist) | |
| brew install gist | |
| # generate docs, upload to gist.github.com, then pipe the Gist URL to Documentation Viewer in your browser: | |
| documentation src | gist -p -f docs.json | awk '{print "https://documentation-viewer.firebaseapp.com/#"$1}' | browser-pipe |
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
| // A very light-weight templating function | |

| I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace | |
| so it's better encapsulated. Now you can have multiple random number generators | |
| and they won't stomp all over eachother's state. | |
| If you want to use this as a substitute for Math.random(), use the random() | |
| method like so: | |
| var m = new MersenneTwister(); |
