This is usually just syntax sugar as the costant enums are inlined in compiled JavaScript.
For instance the following code

The ConstainsKey method is the way to know if a key already exists in the Dictionary.
This come in handy for data reduction. In the sample below, each time we encountner a new word, we add it as a key in the dictionary, else we increment the counter for this specific word.

With Mongoose, everything is derived from a Schema. Lets create a schema.
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var AutoSchema = new Schema({
name : String,
countOf: Number,
});

// by default the collection...
For inserting a new document in the collection, we create a object of the schema.
var Auto = require('models/auto')
var autoObj = new Auto({
name: "NewName",
countOf: 10
});
We save it like the following
autoObj.save(function(err, insertedAuto) {
if (err) return cons...
To call a list of goals as if it were a conjunction of goals, combine the higher-order predicates call/1 and maplist/2:
?- Gs = [X = a, Y = b], maplist(call, Gs).
Gs = [a=a, b=b],
X = a,
Y = b.
The names of modules follow the filesystem's hierarchical structure. With the following file layout:

Bar.hs
the module headers would look like this:
-- file Foo.hs
module Foo where
-- file Bar.hs
module Bar where
-- file Foo/Bar.hs

Recursive functions can get quite expensive. If they are pure functions (functions that always return the same value when called with the same arguments, and that neither depend on nor modify external state), they can be made considerably faster at the expense of memory by storing the values already...
