How to change programming language to solve the project Euler challenge because i am very comfortable with c++

Tell us what’s happening:

Your code so far

function multiplesOf3and5(number) {
// Good luck!
return true;

I’m afraid that functionality is not available on the FCC curriculum. The test kits for Project Euler are written for JavaScript.

However, you can see what the tests will pass to your function and what they return, so you could write your code in C++ in your own IDE and test it yourself.

you can go to the original Euler project and work from there. Here on freecodecamp it works only in javascript, but maybe somewhere else…

The basic syntax between C/C++ and Javascript is pretty similar. Personally I think it’s worth it to try using Javascript.
