338/**
339 Webpack + React 17 fails to compile on any of the following because webpack
340 complains that `startTransition` doesn't exist in `React`:
341 * import { startTransition } from "react"
342 * import * as React from from "react";
343 "startTransition" in React ? React.startTransition(() => setState()) : setState()
344 * import * as React from from "react";
345 "startTransition" in React ? React["startTransition"](() => setState()) : setState()
346
347 Moving it to a constant such as the following solves the Webpack/React 17 issue:
348 * import * as React from from "react";
349 const START_TRANSITION = "startTransition";
350 START_TRANSITION in React ? React[START_TRANSITION](() => setState()) : setState()
351
352 However, that introduces webpack/terser minification issues in production builds
353 in React 18 where minification/obfuscation ends up removing the call of
354 React.startTransition entirely from the first half of the ternary. Grabbing
355 this exported reference once up front resolves that issue.
