Read this error message pattern

Understanding how AI structures error responses from a backend API.

typescript
async function createPost(title: string, content: string) {
  if (!title.trim()) {
    throw new Error('Title is required')
  }
  if (content.length < 10) {
    throw new Error('Content must be at least 10 characters')
  }

  const response = await fetch('/api/posts', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ title, content })
  })

  if (!response.ok) {
    const error = await response.json()
    throw new Error(error.message)
  }

  return response.json()
}
