Function Code

  function extractCodeSection(content: string): string {
  const codeMatch = content.match(/```[\w-]+\s+showLineNumbers([\s\S]*?)```/);
  return codeMatch ? codeMatch[1].trim() : '';
}

Parameters

- `content`: string - The string containing the Markdown-like content to parse for code blocks.

Return Value

const markdownContent = `

\`\`\`typescript showLineNumbers
function add(a: number, b: number): number {
  return a + b;
}
\`\`\`
 
Some text after the code block.
`;
 
const extractedCode = extractCodeSection(markdownContent);
console.log(extractedCode);
 
// Output:
// function add(a: number, b: number): number {
//   return a + b;
