// Let's say you have a function that does some async operation inside setTimeout (think of polling for data)

function runInterval(callback, interval = 1000) {
  setInterval(async () => {
    const results = await Promise.resolve(42) // this might fetch some data from server
    callback(results)
  }, interval)

// EXAMPLE 1

// Let's say you want to create a function that returns different types based on argument passed. Contrived example:

function returnNumberOrString(returnString: boolean) {
    if (returnString) {
        return "42" as string // cast to string to avoid literal type
    }
    return 42 as number // cast to number to avoid literal type

While a lot of Node.js guides recommend using JWT as an alternative to session cookies (sometimes even mistakenly calling it "more secure than cookies"), this is a terrible idea. JWTs are absolutely not a secure way to deal with user authentication/sessions, and this article goes into more detail about that.

Secure user authentication requires the use of session cookies.

Cookies are small key/value pairs that are usually sent by a server, and stored on the client (often a browser). The client then sends this key/value pair back with every request, in a HTTP header. This way, unique clients can be identified between requests, and client-side settings can be stored and used by the server.

Session cookies are cookies containing a unique session ID that is generated by the server. This session ID is used by the server to identify the client whenever it makes a request, and to associate session data with that request.
