/**
 * mock golang defer
 *
 * @remarks
 * defer can register a series of functions. These functions will be automatically executed in the order of first-in, last-out when defer is destroyed. Usually, you can use defer in a function scope to automatically release resources. For example, after a function opens the database, you can 'close the database' register in defer, which ensures that the database will definitely be released when the function ends
 *
 * @example
 * ```
 *  Defer.async(async (d) => {
 *     const db = await openDB() // open resource
 *     // close db
 *     d.defer(async () => await db.close())
 *     const f = await openFile('date.log') // open resource
 *     // close file
 *     d.defer(async () => await f.close())
 *
 *     // some logic code logic
 *     const text = await f.readAll()
 *     const result = await db.set('log', text)
 *
 *     return result // After the function returns, defer will call the registered cleanup function according to the first in, last out
 * })
 * ```
