| /** |
| * These are types for things that are present in the React `canary` release channel. |
| * |
| * 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/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/canary' |
| * ``` |
| * |
| * It is also possible to include it through a triple-slash reference: |
| * |
| * ```ts |
| * /// <reference types="react/canary" /> |
| * ``` |
| * |
| * Either the import or the reference only needs to appear once, anywhere in the project. |
