Code quality

[matiboy]

Please have a look at your code again and propose code quality improvements. Here are some ideas:

• do we need keys in the component (or injectable) or is counts sufficient (how?)
• could toLowerCase be used more efficiently than in a loop
• wouldn't a .forEach be more relevant than the for loop (line 24)
• think of a "better/more modern" way than to check for undefined to validate the presence of a key in an object
• replace this code

  if (this.counts[word] === undefined) {
        this.counts[word] = 1;
        this.keys.push(word);
      } else {
        this.counts[word]++;
      }

  with a one-liner
