10 Programming Languages You Should Learn Right Now

1. Java

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: Java is a class-based, object-oriented programming language developed by Sun Microsystems in the 1990s. It's one of the most in-demand programming languages, a standard for enterprise software, web-based content, games and mobile apps, as well as the Androidoperating system. Java is designed to work across multiple software platforms, meaning a program written on Mac OS X, for example, could also run on Windows.

Where to learn it: Udemy, Lynda.com, Oracle.com, LearnJavaOnline.org.

2. C Language

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: A general-purpose, imperative programming language developed in the early '70s, C is the oldest and most widely used language, providing the building blocks for other popular languages, such as C#, Java, JavaScript and Python. C is mostly used for implementing operating systems and embedded applications.

Because it provides the foundation for many other languages, it is advisable to learn C (and C++) before moving on to others.

3. C++

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: C++ is an intermediate-level language with object-oriented programming features, originally designed to enhance the C language. C++ powers major software like Firefox, Winampand Adobe programs. It's used to develop systems software, application software, high-performance server and client applications and video games.

4. C#

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: Pronounced "C-sharp," C# is a multi-paradigm language developed by Microsoft as part of its .NET initiative. Combining principles from C and C++, C# is a general-purpose language used to develop software for Microsoft and Windows platforms.

Where to learn it: Udemy, Lynda.com, Microsoft Virtual Academy, TutorialsPoint.com.

5. Objective-C

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: Objective-C is a general-purpose, object-oriented programming language used by theApple operating system. It powers Apple's OS X and iOS, as well as its APIs, and can be used to create iPhone apps, which has generated a huge demand for this once-outmoded programming language.

Where to learn it: Udemy, Lynda.com, Mac Developer Library, Cocoa Dev Central, Mobile Tuts+.

6. PHP

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: PHP (Hypertext Processor) is a free, server-side scripting language designed for dynamic websites and app development. It can be directly embedded into an HTML source document rather than an external file, which has made it a popular programming language for web developers. PHP powers more than 200 million websites, including Wordpress, Digg andFacebook.

Where to learn it: Udemy, Codecademy, Lynda.com, Treehouse, Zend Developer Zone,PHP.net.

7. Python

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: Python is a high-level, server-side scripting language for websites and mobile apps. It's considered a fairly easy language for beginners due to its readability and compact syntax, meaning developers can use fewer lines of code to express a concept than they would in other languages. It powers the web apps for Instagram, Pinterest and Rdio through its associated web framework, Django, and is used by Google, Yahoo! and NASA.

Where to learn it: Udemy, Codecademy, Lynda.com, LearnPython.org, Python.org.

8. Ruby

IMAGE: MASHABLE COMPOSITE. IMAGE: WIKIMEDIA COMMONS

What it is: A dynamic, object-oriented scripting language for developing websites and mobile apps, Ruby was designed to be simple and easy to write. It powers the Ruby on Rails (or Rails) framework, which is used on Scribd, GitHub, Groupon and Shopify. Like Python, Ruby is considered a fairly user-friendly language for beginners.

Where to learn it: Codecademy, Code School, TryRuby.org, RubyMonk.

9. JavaScript
