Hi everyone! CodeForces is a very popular platform in the world of sort programming and it's sad to see that it use like 5 years old JavaScript, according to http://codeforces.me/blog/entry/79 I do remember it was a pain to program in JS here in comparison to hackerrank or leetcode (which both support ECMAScript 6). It would be amazing to use the world's the most popular programming language https://www.simplytechnologies.net/blog/2018/4/11/why-is-javascript-so-popular here for recreational sports programming. I bet lots of people use it at work. Thanks.
