-# promise-all-reject-late
-
-Like Promise.all, but save rejections until all promises are resolved.
-
-This is handy when you want to do a bunch of things in parallel, and
-rollback on failure, without clobbering or conflicting with those parallel
-actions that may be in flight. For example, creating a bunch of files,
-and deleting any if they don't all succeed.
-
-Example:
-
-```js
-const lateReject = require('promise-all-reject-late')
-
-const { promisify } = require('util')
-const fs = require('fs')
-const writeFile = promisify(fs.writeFile)
-
-const createFilesOrRollback = (files) => {
- return lateReject(files.map(file => writeFile(file, 'some data')))
- .catch(er => {
- // try to clean up, then fail with the initial error
- // we know that all write attempts are finished at this point
- return lateReject(files.map(file => rimraf(file)))
- .catch(er => {
- console.error('failed to clean up, youre on your own i guess', er)
- })
- .then(() => {
- // fail with the original error
- throw er
- })
- })
-}
-```

-## API
-
-* `lateReject([array, of, promises])` - Resolve all the promises,
- returning a promise that rejects with the first error, or resolves with
- the array of results, but only after all promises are settled.
