[Feedback] try catch blocks in the code samples

Feedback:
It seems to me that code samples for the Node.js are a bit frustrating on the try catch blocks

• with this sample the error will end up in the body attribute of the response

async function getItem(){
  try {
    const data = await docClient.get(params).promise()
    return data
  } catch (err) {
    return err
  }
}

exports.handler = async (event, context) => {
  try {
    const data = await getItem()
    return { body: JSON.stringify(data) }
  } catch (err) {
    return { error: err }
  }
}

I know that it's to show the general approach only, but I would still suggest to remove the getItem as a separate function, or to add some ifs in the main function to handle the getItem returned value

Sorry if I miss something here
