Usage 📝

import React from 'react';

function TextAnalyzerExample() {
  const text =
    'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.';
  const searchTerm = 'Lorem';

  const {
    wordCount,
    charCount,
    sentenceCount,
    paragraphCount,
    searchFrequency,
    readingTime,
    mostFrequentWord,
    leastFrequentWord,
    mostFrequentCharacter,
    leastFrequentCharacter,
  } = useTextAnalyzer({ text, searchTerm });

  return (
    <div>
      <h2>Text Analysis Result</h2>
      <p>
        Estimated reading time: {readingTime.minutes}m {readingTime.seconds}s
      </p>
      <p>Total reading time in seconds: {readingTime.total}</p>
      <p>Human-readable reading time: {readingTime.text}</p>
      <p>
        Search frequency of '{searchTerm}': {searchFrequency}
      </p>
      <p>Word count: {wordCount}</p>
      <p>Character count: {charCount}</p>
      <p>Sentence count: {sentenceCount}</p>
      <p>Paragraph count: {paragraphCount}</p>
      <p>Most frequent word: {mostFrequentWord}</p>
      <p>Least frequent word: {leastFrequentWord}</p>
      <p>Most frequent character: {mostFrequentCharacter}</p>
      <p>Least frequent character: {leastFrequentCharacter}</p>
    </div>
  );
}
