Async Error Handling (try/catch)

I've been working on updating some of my older code to use async/await, and it's been going well, but I'm still uncertain around the best practices for error handling. I just read through this post - http://thecodebarbarian.com/async-await-error-handling-in-javascript.html and I think I get the idea, but wanted to double check.Here's a basic example:async function getData(database, queryString) { // Connect to database, run queryString, and get datas const datas = await connectToSomeDatabase(database, queryString); if (datas) return datas; } async function mailer(subject, message) { // Send an email to let me know that an error occurred await sendAnEmail(subject, message); } async function run() { try { const datas = await getData(var1, var2); if (datas === 'something') { // I've got data so I'll do something with it here } else { // I don't have data so I'm all done } } catch (error) { await mailer('Error!', 'Oops, there was an error, go check the logs.'); console.error(error.stack); } } run(); Is just having try/catch inside my run() function enough to capture any errors that occur in either getData or mailer? Or might some errors slip through the cracks?
