TIOBE Index for June 2020

June Headline: Rust enters the TIOBE index top 20 for the first time

Almost 10 years after its birth, programming language Rust enters the TIOBE index top 20 for the first time. Is this surprising? Rust has been awarded "the most loved programming language" by Stackoverflow users for the last 5 years. In a row! The main reason for this is that Rust is a system programming language that is done right. All the verbose programming and sharp edges of other languages are solved by Rust while being statically strongly typed. Its type system prevents run-time null pointer exceptions and memory management is calculated compile-time. So no garbage collection that suddenly kicks in. We have D, Lua and Julia trying to beat C and C++ but Rust seems to be the first one to come really close. Let's see whether it can keep this top 20 position in the years to come. - Paul Jansen CEO TIOBE Software

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.

This Month's Changes in the Index

This month the following changes have been made to the definition of the index:

• Zbynek Fiala pointed out that according to Wikipedia Delphi and Object Pascal have been merged together again. At least the Delphi page states now "The language [Delphi] is also called Object Pascal.". So as of this month Delphi and Object Pascal are grouped together again.

• There are lots of mails that still need to be processed. As soon as there is more time available your mail will be answered. Please be patient.

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 " programming", also other queries such as "programming with ", " development" and " 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.

Frequently Asked Questions (FAQ)

• Q: Am I allowed to show the TIOBE index in my weblog/presentation/publication?

  A: Yes, the only condition is to refer to its original source "www.tiobe.com".

• Q: How may I nominate a new language to be added to the TIOBE index?

  A: If a language meets the criteria of being listed (i.e. it is Turing complete and has an own Wikipedia entry that indicates that it concerns a programming language) and it is sufficiently popular (more than 5,000 hits for +" programming" for Google), then please write an e-mail to tpci@tiobe.com.

• Q: I would like to have the complete data set of the TIOBE index. Is this possible?

  A: We spent a lot of effort to obtain all the data and keep the TIOBE index up to date. In order to compensate a bit for this, we ask a fee of 5,000 US$ for the complete data set. The data set runs from June 2001 till today. It started with 25 languages back in 2001, and now measures more than 150 languages once a month. The data are available in comma separated format. Please contact sales@tiobe.com for more information.

• Q: Why is the maximum taken to calculate the ranking for a grouping, why not the sum?

  A: Well, you can do it either way and both are wrong. If you take the sum, then you get the intersection twice. If you take the max, then you miss the difference. Which one to choose? Suppose somebody comes up with a new search term that is 10% of the original. If you take the max, nothing changes. If you take the sum then the ratings will rise 10%. So taking the sum will be an incentive for some to come up with all kinds of obscure terms for a language. That's why we decided to take the max.

  The proper way to solve this is is of course to take the sum and subtract the intersection. This will give rise to an explosion of extra queries that must be performed. Suppose a language has a grouping of 15 terms, then you have to perform 32,768 queries (all combinations of intersections). So this seems not possible either... If somebody has a solution for this, please let us know.

• Q: What happened to Java in April 2004? Did you change your methodology?

  A: No, we did not change our methodology at that time. Google changed its methodology. They performed a general sweep action to get rid of all kinds of web sites that had been pushed up. As a consequence, there was a huge drop for languages such as Java and C++. In order to minimize such fluctuations in the future, we added two more search engines (MSN and Yahoo) a few months after this incident.

Java是一种开发者用来创造计算机应用的语言，我们在下载程序需要Java运行环境并且确保它安装在我们的系统上，其中Java也是一些web插件允许我们在浏览器中运行的应用。Java开发人员的需求量是很大的，也就是好找工作。缺点就是比C++更占内存。

Python是服务端的解释器。开源非编译语言，它可以用于自身或者是其他的框架当中。Python是很易于学习的，而且库多而且很多好用的库都是免费的。缺点在于Python是解释型的语言，相对来说比编译语言慢很多。

C语言作为很多大学的计算机专业基础，也是开发固件或者是移动引用的理想语言，一般是用在编写系统软件。优点在于高度可移动的语言，也就是我们在编程的时候不做改动或者是很小的改动。这样的情况下，我们可以开发运行在不同的平台。缺点在于运行时间慢，没有检查机制。因为不支持面向对象，所以后来有了C++。其实C语言并不适合入门，因为很难，但是有是其他语言的鼻祖。学会后接触其他语言很简单，所以学习曲线也是它的缺点。

  目前Java和Python这两门语言使用会比较多一些，相比来说Python比较好就业，看你自己的需求了。
