 Bootstrap provides `data-` attributes that can make toasts appear; however, since we are creating these in script, we need to use their JavaScript functions. The message coming from the server has the format `TYPE|||The message`. Let's look at [the showToast function][v3-toast] (the largest custom JavaScript function in the entire application):
 
 ```javascript
-showToast (message) {
+const mpj = {
+  // ...
+  showToast (message) {
     const [level, msg] = message.split("|||")
   
     let header

     document.getElementById("toasts").appendChild(toastEl)
     new bootstrap.Toast(toastEl, { autohide: level === "success" }).show()
+  },
+  // ...
 }
 ```
 
 Here's what's going on in the code above:

 _(If you've never used JavaScript to create elements that are added to an HTML document, this probably looks weird and verbose; if you have, you look at it and say "they're not wrong...")_
