Project Euler - how far along in JS?

I’m halfway through the ES6 lessons. How far along in Javascript challenges do we need to be to work ProjectEuler100 challenges?

Cheers

You can learn as you go! I’m using the #ProjectEuler100 challenge to learn C++. It means I’ll be slower, but I’m still planning to chug through. 1 down, 99 to go.
