MongoDB 3.2.x Reporting

The find() operator creates a cursor to the data. The client can then parse through the data and do calculations on the data for reports purposes. However, with large data sets this is not practical. It makes far more sense for the server to do the calculations and return the result. This can save a considerable amount of unnecessary network traffic. You can however run the count on the cursor without much overhead.

db.mycollection.find().count()

Mongo has two other methods for reporting on data:

• Aggregation
• Map-Reduce

var uniqueArray = function(arrArg) {
  return arrArg.filter(function(elem, pos,arr) {
    return arr.indexOf(elem) == pos;
  });
};

var uniqEs6 = (arrArg) => {
  return arrArg.filter((elem, pos, arr) => {
    return arr.indexOf(elem) == pos;
  });

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
