TIOBE Index for April 2015

April Headline: Java back at the top!

Java is back at the top of the TIOBE index after one and half year. Androids ongoing success is probably the major reason for Java's revival. The Java language has been in slow decline for many years now, mainly due to its waning foot print in the enterprise server back end market. Since October last year the increasing demand on Java Android programming has exceeded this decline, thus pushing Java more than 3% during this period. Another interesting move this month concerns Scala. The functional programming language jumps to position 25 after having been between position 30 and 50 for many years. Scala seems to be ready to enter the top 20 for the first time in history.

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.
