Support for Java and JavaScript
Now you can solve our problems in both Java and JavaScript:

While the lessons are still Python-only, the problems can also be used to teach or learn Java and JavaScript. If you teach these languages, you’ll see the progress of your students in the teacher’s dashboard no matter what language was used to solve the problem.
As our problems are input/output ones — the program should read the data, perform calculations and print the result — we introduced custom functions input() and print() in JavaScript. input() reads an entire string from the input, print() prints a string on a separate line (i.e. followed by a trailing newline character). Solutions in Java may use any IO solutions from the standard library.
Props to our engineers Andrey Tkachev and Tamerlan Tabolov.
