Top 10 Programming Languages in world?

Now these are the Top 10 programming languages in 2015 by IEEE Spectrum and they usually conducts this procedure and every year and these are the rankings of 2015.

1. Java
With almost 100/100 points in their ranking, java still stays top in the list and it's unmovable at that spot.

2. C

3. C++

4. Python

5. C#

6. R

7. PHP

8. Java Script

9. Ruby

10. Matlab

It's better to follow these rankings and also this website for your future information on these.

IEEE spectrum is the website and here is the website link for more details.

Well, as stated above the official list of top programming languages is ranked by IEEEE spectrum. The list reads
1. Java
2. C
3. C++
4. Python
5. C#
6. R
7. PHP
8. Javascript
9. Ruby and
10. Matlab

The spectrum ranking for the top three stand apart by a whisker with Java getting 100, C 99.9 and C++ 99.4. The language R has been a big gainer in 2015 which has moved from 9th to 6th place.

IEEE's comparison is based on the language preference rather than performance. If we go by performance wise then you won't find the languages with virtual machine compilers at the top. If you want to answer for academic purpose the go with IEEE's list for languages.

In case of finding the top language based on performance you need to check out the language performance comparison to see which language is at the top.

1. C
2. C#
3. D
4. GO
5. JavaScript
6. Lua
7. Java
8. Python
9. Perl
10. R
11. Ruby

All of my techulator fellows gave correct answer as per IEEE spectrume. But as you asked which language is at the top in present than we can't rely on IEEE. First of all there are two type of development environment on which language decisions relies on - Standalone (Offline development everything which can't be used in a Browser comes under Standalone Development) or Web (Application which can be only used in Web Browser comes under this category) Development.
Languages used for Standalone Development
1. JavaScript
2. Python
3. C
4. Java
5. C++

Languages used for Web Development
1. Ruby
2. JavaScript
3. Python
4. PHP

JavaScript and Python managed to get position in both Standalone and Web Development because of their versatile nature. JavaScript can be used for developing Windows and Android Application whereas Python is giving tough competition to PHP in terms of back-end usage. Apart from that Python can be also used for managing large Database due to its speed. Java and C++ were toppers long time ago but they are now not good as they were before. All the function which they were used to do, are now done by other language but in less time and less coding. JavaScript is the most powerful language in this era because it gives you better job benefits and its easy to use as well.

As I see, "Top programming language in the world" depends on the field of your programming. Every fields such as Web development, Gaming, Operating System, etc has their own pattern of programming. As I would say, Programming language for Web Development are HTML, Css, PHP, JavaScript, etc. So, I think you should be clear about the Category of Field on which you are asking for.

Regarding Web Development, I see JavaScript is becoming a dominant Language over other languages such as Php, Python, etc. As JavaScript is used for both the front-end and back-end.

The benefit of using Single Programming language for both back-end and front-end is that it helps to remove Context Switching.

Context Switching means switching from one language to another. The effects of context switching are painfull:

1. If I am working on something, and I have to start doing something else, it can take ages before I am actually working on the new task.
2. Because I have to switch contexts multiple times a day, I feel that I cannot get anything done (often this isn't just a feeling).

So, JavaScript is becoming popular now a days. It doesn't mean that php, python are not good. They have their excellence on their own fields.

Sorting the programming languages, I would list as listed by joy jooon.

Languages used for Standalone Development
1. JavaScript
2. Python
3. C
4. Java
5. C++

Languages used for Web Development
1. Ruby
2. JavaScript
3. Python
4. PHP

Top programming languages

1. Javascript
Javascript is the most popular language among developers successively for 6 years, and also according to Stackoverflow. It's vital to front end development and increasingly relevant to back - end development

2. Python
Python has been a growing language and it shows no signs of disappearing. You will find it in web applications, desktop apps, network servers, machine learning, media tools and more.

3. Rust
If you haven't heard about Rust before, it's a new system-level programming language that is changing the way we think about programming. It came in the first place in 2018 Stackoverflow developer survey for developer most loved and waned language.

4. GO
Go is a minimal language like Python since it is developed by Google, who are also Python lovers. They came up with a language which is simple to write like Python but more efficient like C++. GO provides better features to write concurrent programs.

5. Swift
If you want to get into iOS mobile development, you should definitely consider Swift as a highly paid career path.

6. KOTLIN
Kotlin is the second most loved and wanted a programming language according to Stackoverflow survey.
Language is originally developed by Jet brains. It is fully interoperable with Java and comes with no limitations. It can be used almost everywhere Java is used today.

7. C++
C++ is a highly efficient and flexible language. first created back in 1985. It has remained in high demand due to high performance, reliability, and variety of contexts you can use it.

8.TYPESCRIPT
Typescript is a programming language designed for large-scale Javascript application development.

9. JAVA
Java is arguably the most popular programming language you would have ever heard about.

10. F#
F# is originally developed by F# Software Foundation. There was time nothing much was happening in the web regarding off F# but according to the latest survey F# ranks in highest salary comparative to other programming languages. F# is most often used as a crossed platform common language infrastructure language. But it can also generate Javascript and GPU code.
