7The idea is simple: you write down a javascript snippet (named vals) in your browser, and it's instantly executed on a server. You can use it to:
8
9- execute a function on a cron schedule
10- host a small websites (this article [hosted on Val Town](https://www.val.town/v/pomdtr/love_letter))
11- send yourself emails
32
33// run every hour
34export default function(interval: Interval) {
35    // create the val table
36    await options.sqlite.execute(createQuery);
78
79// triggered each time an email is sent to pomdtr.sqlite_email@valtown.email
80export default async function(email: Email) {
81  // forward the email to my own email address
82  await sendEmail({
96## Publishing the Table
97
98The val.town stdlib provides a neat `rpc` function that provides a simple way to expose a function as an API. So I decided to write a simple val that would run a query on the table, and return the result.
