Lambda expression vs method reference [closed]
...t is crystal clear what it does. Very often (but not always!) method refs win on this metric, so we included them as an option, to be used in those cases.
A key consideration about whether method refs clarify or obfuscate intent is whether it is obvious from context what is the shape of the func...
Mongoose populate after save
...ocs.
This one works on models and returns a promise. It's therefore used a bit differently:
book.save(function(err, book) {
Book // Book not book
.populate(book, { path: '_creator'})
.then(function(book) {

How do I create a Java string from the contents of a file?
...e contents (a byte array), and the decoded characters (each of which is 16 bits even if encoded as 8 bits in the file) reside in memory at once. It is safest to apply to files that you know to be small relative to the available memory.
