What is the oldest tutorial on Sololearn?

Question

Is it html?

Answer 1

Sonic
Publishing dates of the separate apps (from Google Play):

HTML 29.08.2013
CSS 27.10.2013
JavaScript 12.03.2014
C++ 17.06.2014
PHP 28.08.2014
SQL 02.09.2014
Java 22.12.2014
Swift 10.09.2015
Python 12.10.2015
C# 28.03.2016
Ruby 03.12.2016
jQuery 29.12.2016

C has no own android app.
Kotlin has also not an own app.

Edit:
The SL app was published on 25.10.2016.
So I think they used the separate apps (and lessons) to build this app.

Answer 2

That's a neat method Denise Roßberg . May not be accurate as the dates are for the comments and not the tutorials but should be pretty close. Good work. Full marks for thinking outside the box!

Answer 3

You can try this:

Search the introduction lesson (Welcome to Java!/Python!...), search the first comment.

Welcome to Java -> 12.05.2015
Welcome to HTML -> 03.07.2015
Welcome to Python -> 12.01.2016
Welcome to C++ -> 31.03.2015
... (I got tired :D)

I think C++ could be the first (followed by Java and HTML).

Answer 4

might be c++
😂😂

Answer 5

Sonic They should happen on the same day IF comments were enabled when the tutorial was released.

Answer 6

Thanks for the research Denise Roßberg. You get best answer for your efforts!

Answer 7

BTW, the first ever language tutorials were only available as separate apps before they consolidated the tutorials into a single app, added comments and community etc. so the order of comments might be quite different from the order of adding language tutorials which used to be separate apps. I did play around with the original separate language apps in 2015 a bit. The languages I remember being there then are html, css, js, php, c++, Java though I don't know the order they were added . Then came sql, swift, etc. I think ruby and python came afterwards. The newest ones are C#, jquery and c I think.

Answer 8

MöHäN Aggarwal
I was just guessing that. 😂😂😂

Answer 9

Sonic This works only if it was immediately possible to comment a lesson. (I can not imagine that nobody writes a comment if he see that he can do it ;))

Answer 10

SPACE c++ isn't an ancient language and it is not funny either😒😒😒

Answer 11

Could be HTML or CSS

Answer 12

Denise Roßberg Not incredibly likely but does mean that there is a chance (e.g. Me)

Answer 13

Sonic Thank you :)

Answer 14
