Programming Languages
Java
Java is the most used language worldwide with 9 million Java developers. Java is the language of the Android mobile operating system. Android provides all of the tools and APIs necessary to develop applications for its Android OS using the Java programming language. Literally, there are tons of Java applications needing to be supported, updated and maintained.
Microsoft’s .NET
The Microsoft .NET Framework is a software framework. Microsoft’s .NET includes a large library of coded solutions, and a virtual machine that manages program execution. The framework's Base Class Library provides a large range of features including user interface, data and data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications.
C#
C# ranked No. 6 on the most-recent TIOBE Index. C# is a multi-paradigm programming language that includes imperative, functional, generic, object-oriented and component-oriented programming disciplines. There are fewer C# developers than Java developers, but C# is an important component of Microsoft.
C/C++
C++ builds on C and is an extension of the C language. C++ involves key application domains from systems software, application software, device drivers, embedded software, high-performance server and client applications, to include entertainment software such as video games. C and C++ ranked No. 2 and 3, respectively, on the most-recent TIOBE Index. C++ is a great influence upon many other popular programming languages, most notably its influence upon Java.
JavaScript (along with CSS and HTML)
JavaScript is the language of the Web. It powers all of the popular Web browsers. JavaScript is ranked No. 11 on the most-recent TIOBE Index.
Visual Basic
Visual Basic was designed to be used by beginner programmers. From using simple GUI applications or further developing complex applications, Visual Basic has too much code in use to be ignored. Visual Basic is a combination of visually arranging components or controls on a form specifying attributes and actions of those components, and writing additional lines of code for more functionality. Visual Basic ranked No. 5 on the most-recent TIOBE Index.
PHP
PHP is a Web-only, server-side language. PHP was designed as a general-purpose scripting language. PHP originally designed for Web development to produce more dynamic Web pages online. PHP is ranked No. 4 on the most-recent TIOBE Index. PHP is considered a good language for freelancers.
Objective-C
Objective-C borrows heavily from Smalltalk and the C language. Objective-C influenced the creation of Java. Objective-C is used primarily on Apple's Mac OS X and iOS. Objective-C developers work on very intense high-pressure projects and are in short demand. Apple's iPhone, iPod Touch and iPad programming relies upon Objective-C. Objective-C ranked No. 9 on the most-recent TIOBE survey, but that is moving way up from being No. 45 in the survey in June of 2009.
Perl
Like the Latest Designers say “Perl is the new COBOL”. Perl is among several dynamic or scripting languages which include Python, PHP and Ruby. Perl is tracking higher in demand as it is considered as the duct tape of the internet for solving problems. Perl was ranked No. 8 on the most-recent TIOBE Index.
Python
Dynamic languages, such as Python, are being used to create Web/cloud applications on frameworks such as Django. The Google App Engine is built with Python and originally only supported Python. Perl and Python are both general purpose languages with usage in multiple industries, from aerospace and defense to sciences and to financial to hi-tech. Python was ranked No. 7 on the most-recent TIOBE Index.
Ruby
Ruby originated in Japan and interest in the language outside of Japan grew as its dynamic properties became known. Ruby is a language that carefully balances blending Perl, Smalltalk, Eiffel, Ada, and Lisp. Ruby is used for building Web apps, simulations, 3D modeling, business apps, robotics, networking, and telephone system administration systems among other uses. Ruby supports multiple programming paradigms, including functional, object oriented, imperative and reflective. It also has a dynamic type system and automatic memory management.
