value', then the return value should be 'data'. Today, you have to write 'data.key = value; data'. I want that last part to be implicit, but only if you mutate the data variable. And there should be a command-line flag "--retval={expr,data,auto}", with 'auto' being the ...
Run Underscore.js in noConflict mode, returning the _ variable to its previous owner. Returns a reference to the Underscore object. _.noConflict = function() { root._ = previousUnderscore; return this; };¶ Keep the identity function around for default iteratees. _.identity = function(...
(b) Variable Argument SequenceWe can convert sequence into variable arguments using 'seqName: _*' with type ascription.For example,def product(args: Int*): Int = { args.fold(1)(_ * _) } val factors = Seq(2, 3, 4) val productOfFactors = product(factors: _*) // Convert the ...
