// LIMITATIONS: There's some precision loss beyond 3 decimal places
// CONTRIBUTORS: yes please! if you know a more precise way to get
// decimal digits then pls lemme know!
// GetDecimalSymbolAt() could use some more love/precision

A utility hook to parse and type URL search params based on a configuration object. This hook is useful when you want to access URL search params in a typesafe way and with proper casting.
import { useMemo } from "react";
import { useSearchParams } from "react-router-dom";
type ParseConfig = Record<
string,
| { type: "string"; defaultValue?: string }
| { type: "number"; defaultValue?: number }
| { parse: (value: URLSearchParams) => unknown }
>;

What forces layout/reflow. The comprehensive list.

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
