Wonder what app or program is used to build and run SoloLearn?

Question

Dreaming to learn it after I finish some of the preliminary courses, as I have just done two courses only and comparatively in the kindergarten classes still!

Methinks, the SoloLearn App would be for the Post Doctoral people!

I didn't say ASP.net is on its way out but yes ASP.net web forms and classic ASP has basically left already. ASP.net core is well supported by Microsoft and the closed source .net platform is still very popular for software run in Windows. I doubt Microsoft will let ASP.net die any time soon. Smaller pieces of ASP.net could fade away like web forms but the platform should last many more years.

Yes, PHP is popular, has been for about 20 years and probably will continue being popular for many more years.

Answer 2

Indebted Sir, for your response.
I have just done the HTML and JavaScript courses, and I am into CSS right now. So, because of your response, I sure will take up PHP once I get through CSS.

Your guidance, I value, for it brings home to me the value of ASP and PHP to make sites like SoloLearn work so well. And so, thank you, once again for it.

It also makes me admire whoever has done the core for SoloLearn, run so many lessons, with millions of students or subscribers. The volumes are astounding, and I have not seen bugs, downtimes or crashes, yet.

Admirable, I should say!

They're using ASP.net and Azure hosting for the web app.

You can tell they're using Azure hosting in the Code Playground feature because that runs
with the origin https://solocode.azurewebsites.net That's when you run HTML/CSS/JS codes. The https://solocode.azurewebsites.net origin shows in error messages if your AJAX calls violate CORS.

I forget where I saw this but I remember seeing .asp or .aspx extensions in parts of sololearn.com which indicated use of classic ASP or ASP.net web forms. I might have seen it in error messages. ASP.net and Azure are both from Microsoft and fit nicely together.

Since ASP.net web forms is largely replaced with newer ASP.net technologies and most URL's don't include a .aspx or .asp extension, I suspect they're using mostly ASP.net MVC or ASP.net core now.

Answer 4

Sound advice, once again, and valuable to me as I did not know that ASP.net is on its way out. Anyway, I always loved the underdog open source stuff :-)

As to why your choice of PHP for me is valuable is because, in my work I find I have to do a lot of virtual health education, and quizzes, puzzles, simulations, API, and other interactive web pages are the tools that I have to rely on.

Hence, PHP looks the most logical step after HTML, JavaScript, and CSS.

Answer 5

Yes, ASP.net core or PHP would be good now.

Don't try classic ASP or ASP.net web forms because those are too old. Classic ASP was replaced by ASP.net around 2002-2005. ASP.net web forms was replaced around 2010-2013.

☺️Thank you Sir, for the sound advice a couple of months ago, for I just completed PHP in SoloLearn. Now practicing PHP with Challenges. So, step by step taking up the path you drew for me!
Indebted!👌
