Several questions about duplicates in `.phrases`?

[bkardell]

Taking the example from MDN and tweaking it a bit...

const phraseData = [
  { phrase: "azure", boost: 5.0 },
  { phrase: "khaki", boost: 3.0 },
  { phrase: "tan", boost: 2.0 },
  { phrase: "azure", boost: 2.0 },
  { phrase: "khaki" }
];

const phraseObjects = phraseData.map(
  (p) => new SpeechRecognitionPhrase(p.phrase, p.boost),
);

What are the used values of each of these, in practice?
