TIOBE Index for January 2015

January Headline: JavaScript programming language of 2014!

After all these years, JavaScript has finally become TIOBE's language of the year. It was a close finish. Swift and R appeared to be the main candidates for the title but due to a deep fall of Objective-C this month, a lot of other languages took advantage of this and surpassed these two candidates at the last moment.

JavaScript has won the award because it appeared to be the biggest mover of 2014. JavaScript won 1.70% in one year time, followed by PL/SQL (+1.38%) and Perl (+1.33%). The JavaScript programming language has a long history and is always considered as the "ugly duckling" from a language design point of view. Nevertheless, JavaScript has become the standard browser language through the years. Boosted by the successes of JavaScript libraries and frameworks JQuery, Bootstrap, Node.js and GWT, JavaScript really deserves this award.

What about JavaScript's competitors? Both CoffeeScript (from position #170 to #158) and TypeScript (from #205 to #195) hardly moved upwards in 2014. An exception to this is Dart, which made a big leap from position #124 to #34 in 2014. Let's see what happens to Dart in 2015, but it seems JavaScript has no real competition yet.

It is always tempting to try to forecast what will change in 2015. Objective-C will probably lose its dominant position in mobile app development, whereas Java and Swift will gain traction in that field. Java might even become number one of the TIOBE index again. Other trends in progamming are modelling and big data. Here, MATLAB and R appear to be the market leaders. There is a realistic chance that they will enter the top 10 in 2015.

The TIOBE Programming Community index is an indicator of the popularity of programming languages. The index is updated once a month. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.

The index can be used to check whether your programming skills are still up to date or to make a strategic decision about what programming language should be adopted when starting to build a new software system. The definition of the TIOBE index can be found here.

Bugs & Change Requests

This is the top 5 of most requested changes and bugs. If you have any suggestions how to improve the index don't hesitate to send an e-mail to tpci@tiobe.com.

  1. Apart from "<language> programming", also other queries such as "programming with <language>", "<language> development" and "<language> coding" should be tried out.
  2. Add queries for other natural languages (apart from English). The idea is to start with the Chinese search engine Baidu. This has been implemented partially and will be completed the next few months.
  3. Add a list of all search term requests that have been rejected. This is to minimize the number of recurring mails about Rails, JQuery, JSP, etc.
  4. Start a TIOBE index for databases, software configuration management systems and application frameworks.
  5. Some search engines allow to query pages that have been added last year. The TIOBE index should only track those recently added pages.
