What is this the perfect and secured programming languages for data-center websites ?

* No language or framework guarantee you perfect security.

Its a team effort. Architect to design with security in mind. Programmer to write secure code. Sys Admin to harden the web-server and network infrastructures. QA to check for security issues. Hacker to exploit for security areas. And again programmer to secure fix those issues/areas. 

Security mainly depends on how you handle (i.e.) filters (malicious) requests coming from internet. But there are other areas that falls under security like DDOS for example.

* Any language or platform can be used to make secure website.

Hint: If you are on internet don't think you are100% secure :)

Basm Allah Alrahman Alrahim

there are a lot of programming languages for websites any way the most important2 are PHP and ASP.NET for server side

and there is famous and may be the best for client side programming and that is jquery ( advanced javascript )

you cant ignore client side for a lot of reasons the most important one is to make your website faster ( remember that you can make a lot of things with css and HTML to make it more easier especially with browsers like IE that may stop JavaScript some times and you must be professional to deal with IE as a user)

Note

if you are PHP or ASP.NET programer it will be easy to learn jQuery and you will make some small changes between then so you can programed your website twice one for server side by PHP and one for client side with Jquery )

Note

If you are a good programmer you will make a secure website

Note

If you want to be a very good programmer you must study both PHP and ASP.NET and that because there is a lot of servers that just deal with PHP only and Others deal with ASP.NET only and you may have a customer want his website at one of them

thanks for inviting i agree with answers above

There is no perfect and secured programming languages for data center ales, at least put a protective device.

Yes Templete class from language

There is no "perfect" programming language that is universally suitable for all data-center websites. The choice of programming language for a data-center website will depend on a variety of factors, including the requirements of the website, the skills and expertise of the development team, and the resources available. Some languages that are commonly used for data-center websites include Java, C++, and Python. These languages are all powerful and versatile, and they have large communities of developers who can provide support and resources. Ultimately, the choice of programming language will depend on the specific needs of the website and the goals of the development team.

python 

it is the of the best language for hacking into web servers.

You can share it with the language on which you have most grip.

Servers do not need language; its the service running on servers which need applications in different programming languages. You may use ASP, PHP, PY, JAVA or any other language to build your service (application) which will run smoothly on that machine; unless its a RISK based server. 

So use the language you know the Best to build a web-service (app).

If its me, I would have chossen the combo of OS-LINUX (any free version), DB-MYSQL, Appachi as middleware & that will give me an option to use PHP, JAVA or PY as front-end.

Its completly based on the platform you choose and flavor your clients depends upon. ( MVC core flavor with Azure or SQL are trending with intractive of React or angular ) in meanwhile LAMP ( Linux , Apache , Mysql  and PHP) is not stepping back from past many years.

There are Ton's of Technologies emerging , the selection of Programming languages is mainly on the taste .

Final word: All progarmming languages have there unique features and security concern with ultimately parllel to all. The best our algorithm is the best our website flows no matters with languages.
