nodejs-bigtable has @example comments that include code. This is error prone, since it's not compiled and may get obsolete. Instead of inline code, all @examples should refer to a sample file and a tag within it.

nodejs-spanner has a great examples of this. Here's one example (link):

/**
 ...
 * @example <caption>include:samples/batch.js</caption>
 * region_tag:spanner_batch_client
*/
