+When a modifier is present, we likely need to transform the value when reading or syncing it back to the parent. We can achieve this by using the `get` and `set` transformer options:
 
 ```js
 const [modelValue, modelModifiers] = defineModel({
   // get() omitted as it is not needed here
   set(value) {
+    // if the .trim modifier is used, return trimmed value
     if (modelModifiers.trim) {
       return value.trim()
     }
+    // otherwise, return the value as-is
     return value
   }
