To make the output easier to read you can do this instead:
${this.array.join(', ')}

This works, but the code would be better if you only had one instance variable this.array and instead got the total from a function i.e.
total() {
return this.array.length;
}This is better because you don't have to keep track of two variables, you only need one.
