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

VS Code: Debugging

The way we usually debug JavaScript code, is through a web browser and typing the keyword debugger or console.log in our files, but switching between browser and VS Code can be annoying, and we also lose synchronization with the source code.

VS Code provides the extension Debugger for Chrome which enables you to edit, debug, and set breakpoints to your JavaScript

VS Code: Debugging Jest

Sometimes, debugging with console.log is not enough to find out what is happening in the code, as console.log prints only plain objects but neither functions nor objects with circular references. Besides, it's possible you may need to know the context and flow of the code.
