# If you don't remember the exact path/name, search the log for deleted files
git log --diff-filter=D --summary | grep delete
# Find the file you want to get from the ouput, and use the path
# Find the commits that involved that path

What forces layout / reflow

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.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

URLs into Indexed DB, via Service Workers

Let's say you're using Indexed DB for the offline data store for a catalog. One of the object stores contains product images. Wouldn't it be great if you could just have something like this in your catalog page?

<img src="indexeddb/database/store/id">

// Turn on Developer Mode under User Settings > Appearance > Developer Mode (at the bottom)
// Then open the channel you wish to delete all of the messages (could be a DM) and click the three dots on the far right.
// Click "Copy ID" and paste that instead of LAST_MESSAGE_ID.
// Copy / paste the below script into the JavaScript console.
// If you're in a DM you will receive a 403 error for every message the other user sent (you don't have permission to delete their messages).

var before = 'LAST_MESSAGE_ID';
clearMessages = function(){
	const authToken = document.body.appendChild(document.createElement`iframe`).contentWindow.localStorage.token.replace(/"/g, "");
	const channel = window.location.href.split('/').pop();
