Is it possible to change the way of adding a token to the array of tokens like this?:
createTokens(number) {
let tokens = [];
for (let i = 0; i < number; i++) {
let token = new Token(i, this);
tokens[i] = token;
}
return tokens;
}

Also, you can still use "const" since "tokens" is never re-assigned, only indexed.

241,434 PointsNo, they don't. That's why "push" is a good choice in this situation.
