Getting Started with Node.js

2014_08_13_Nodejs1

There was a time when JavaScript was mocked and ridiculed as the language of pop-up and alert messages.

But the language has matured and found a few killer libraries that have earned the respect and love of the development community in not just the browser—but also on the server.

It all started with jQuery, the “write more, do less” library that standardized compatibility across browsers and gave us the power to reliably select and animate elements of a web page or app. We also got the ability to send and receive messages with AJAX (Asynchronous JavaScript and XML), a technology that powered the Web 2.0 movement.

Now there’s a new sheriff in town called Node.js, and it’s leading the way for a new class of web applications.

Code Clinic: 6 Problems in 6 Programming Languages

CodeClinic

“Learn to code!” It’s the latest buzzphrase. Everyone from Barack Obama to Will.i.am is talking up the importance of learning a programming language—which is good. But it’s only part of the story.

Successful programmers know more than just a computer language. They also know how to think about solving problems. They use “computational thinking”: breaking a problem down into segments that lend themselves to computer solutions.

Our Developer content at lynda.com already provides a wealth of programming courses geared towards all levels of experience. Starting this month, we’ll also delve into computational thinking—with a unique new set of courses called Code Clinic.

Getting Started with Excel VBA

excel-cells-in-repose

Excel is a powerful and versatile tool you can use to analyze data—but not every capability you might want is built in.

Using the Visual Basic for Applications (VBA) language, you can script custom processes in Excel. VBA is an object-oriented language, which means that elements of Excel—such as workbooks, worksheets, and the program itself—are represented as objects. An object has three main components:

  • properties, which describe the object
  • methods, which are things the object can do
  • events, which are occurrences the object can recognize and react to
