如何计算特定行后2行的所有行中的单词？

function calculateWordsAfterSpecificLine(text, specificLine) {
  // Step 1: Split text into lines
  const lines = text.split('\n');

  // Step 2: Find the index of the specific line
  const specificLineIndex = lines.findIndex(line => line.includes(specificLine));

  // Step 3: Find the lines after the specific line
  const linesAfterSpecificLine = lines.slice(specificLineIndex + 1, specificLineIndex + 3);

  // Step 4: Merge the lines into a single string
  const mergedLines = linesAfterSpecificLine.join(' ');

  // Step 5: Extract words from the merged string
  const words = mergedLines.split(/\s+/);

  return words;
}

// Example usage
const text = `
Line 1: This is the first line.
Line 2: This is the second line.
Line 3: This is the third line.
Line 4: This is the fourth line.
Line 5: This is the fifth line.
`;

const specificLine = 'Line 2';

const words = calculateWordsAfterSpecificLine(text, specificLine);
console.log(words);
