How can I eliminate repeated words from a map using React?

edit

One way to eliminate repeated words from a map using React is to use a JavaScript Set to store unique words. Here is an example code snippet:

import React from "react";

const words = [
  "apple",
  "banana",
  "cherry",
  "apple",
  "banana",
  "durian",
  "apple",
];

const uniqueWords = [...new Set(words)];

function App() {
  return (
    <div>
      <ul>
        {uniqueWords.map((word, index) => (
          <li key={index}>{word}</li>
        ))}
      </ul>
    </div>
  );
}

export default App;

In the code above, we first create an array of words that contains duplicates. We then create a new array called uniqueWords by spreading a Set instance created from the words array. This Set instance only contains unique words.

We then use uniqueWords in our React component to render a list of unique words inside an unordered list element. We use the map method to iterate over uniqueWords and render a list item for each unique word. We also assign a unique key to each list item using the index parameter that map provides.

This approach allows us to eliminate duplicates from our original data and only render unique words in our React component.
