JavaScript File Structure

The script.js file contains the logic for interacting with the Dictionary API and updating the user interface.

Detailed Breakdown

• Event Listener: This listens for the form submission to trigger the word search.

  form.addEventListener('submit', (e) => {
      e.preventDefault();
      getWordInfo(form.elements[0].value);
  });

• getWordInfo Function: This is an asynchronous function that fetches word information from the API and updates the DOM.

  const getWordInfo = async (word) => {
      document.getElementById("loading").style.display = "block";
      document.getElementById("result").style.display = "none";
  
      try {
          const response = await fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${word}`);
          const data = await response.json();
          let definitions = data[0].meanings[0].definitions[0];
  
          resultDiv.innerHTML = `
              <h2><strong>Word:</strong> ${data[0].word}</h2>
              <p>${data[0].meanings[0].partOfSpeech}</p>
              <p><strong>Meaning:</strong> ${definitions.definition === undefined ? "Not Found" : definitions.definition}</p>
              <p><strong>Example:</strong> ${definitions.example === undefined ? "Not Found" : definitions.example}</p>
              <p><strong>Antonyms:</strong></p>
          `;
  
          if (definitions.antonyms.length === 0) {
              resultDiv.innerHTML += `<span>Not Found</span>`;
          } else {
              for (let i = 0; i < definitions.antonyms.length; i++) {
                  resultDiv.innerHTML += `<li>${definitions.antonyms[i]}</li>`;
              }
          }
  
          document.getElementById("loading").style.display = "none";
          document.getElementById("result").style.display = "block";
  
      } catch (error) {
          document.getElementById("loading").style.display = "none";
          document.getElementById("result").style.display = "block";
          resultDiv.innerHTML = `<p>Word not found. Please try again.</p>`;
      }
  };

Code Explanation

• form: Selects the form element to attach the event listener.

  const form = document.querySelector('form');

• resultDiv: Selects the result div where the output will be displayed.

  const resultDiv = document.querySelector('.result');

• form.addEventListener: Prevents the default form submission and calls the getWordInfo function with the input word.

  form.addEventListener('submit', (e) => {
      e.preventDefault();
      getWordInfo(form.elements[0].value);
  });

• getWordInfo: Fetches data from the Dictionary API and updates the DOM with the word's details.

  const getWordInfo = async (word) => {
      document.getElementById("loading").style.display = "block";
      document.getElementById("result").style.display = "none";
  
      try {
          const response = await fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${word}`);
          const data = await response.json();
          let definitions = data[0].meanings[0].definitions[0];
  
          resultDiv.innerHTML = `
              <h2><strong>Word:</strong> ${data[0].word}</h2>
              <p>${data[0].meanings[0].partOfSpeech}</p>
              <p><strong>Meaning:</strong> ${definitions.definition === undefined ? "Not Found" : definitions.definition}</p>
              <p><strong>Example:</strong> ${definitions.example === undefined ? "Not Found" : definitions.example}</p>
              <p><strong>Antonyms:</strong></p>
          `;
  
          if (definitions.antonyms.length === 0) {
              resultDiv.innerHTML += `<span>Not Found</span>`;
          } else {
              for (let i = 0; i < definitions.antonyms.length; i++) {
                  resultDiv.innerHTML += `<li>${definitions.antonyms[i]}</li>`;
              }
          }
  
          document.getElementById("loading").style.display = "none";
          document.getElementById("result").style.display = "block";
  
      } catch (error) {
          document.getElementById("loading").style.display = "none";
          document.getElementById("result").style.display = "block";
          resultDiv.innerHTML = `<p>Word not found. Please try again.</p>`;
      }
  };

• Loading Indicator: Shows a loading message while fetching data.

  document.getElementById("loading").style.display = "block";
  document.getElementById("result").style.display = "none";

• Data Fetch: Fetches the word data from the Dictionary API.

  const response = await fetch(`https://api.dictionaryapi.dev/api/v2/entries/en/${word}`);

• Data Display: Updates the DOM with the word's meaning, phonetic, part of speech, example, and antonyms.

  let definitions = data[0].meanings[0].definitions[0];
  
  resultDiv.innerHTML = `
      <h2><strong>Word:</strong> ${data[0].word}</h2>
      <p>${data[0].meanings[0].partOfSpeech}</p>
      <p><strong>Meaning:</strong> ${definitions.definition === undefined ? "Not Found" : definitions.definition}</p>
      <p><strong>Example:</strong> ${definitions.example === undefined ? "Not Found" : definitions.example}</p>
      <p><strong>Antonyms:</strong></p>
  `;
  
  if (definitions.antonyms.length === 0) {
      resultDiv.innerHTML += `<span>Not Found</span>`;
  } else {
      for (let i = 0; i < definitions.antonyms.length; i++) {
          resultDiv.innerHTML += `<li>${definitions.antonyms[i]}</li>`;
      }
  }

• Error Handling: Displays an error message if the word is not found.

  } catch (error) {
      document.getElementById("loading").style.display = "none";
      document.getElementById("result").style.display = "block";
      resultDiv.innerHTML = `<p>Word not found. Please try again.</p>`;
  }
