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

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Beyond any other definition, Behavior Driven Development/Design ("BDD") is a philosophy.

What is "BDD"?

"BDD" is a set of tools and techniques that exist to support one idea: good software is written to meet the needs of the stakeholders (typically clients).

These stakeholders know their business better than the people designing the software. It is the responsibility of developers to capture the business requirements and translate them into software.

BDD tools facilitate this as a process by letting developers author features first, which capture requirements in a domain-specific language. Code is developed by working on these high-level features, and then on code specifications.
