@types/react-is/canary.d.ts

/**
 * These are types for things that are present in the React 18 alpha.
 *
 * Once React 18 is released they can just be moved to the main index file.
 *
 * To load the types declared here in an actual project, there are three ways. The easiest one,
 * if your `tsconfig.json` already has a `"types"` array in the `"compilerOptions"` section,
 * is to add `"react-is/canary"` to the `"types"` array.
 *
 * Alternatively, a specific import syntax can to be used from a typescript file.
 * This module does not exist in reality, which is why the {} is important:
 *
 * ```ts
 * import {} from 'react-is/canary'
 * ```
 *
 * It is also possible to include it through a triple-slash reference:
 *
 * ```ts
 * /// <reference types="react-is/canary" />
 * ```
 *
 * Either the import or the reference only needs to appear once, anywhere in the project.
