`innerText` is a property of the `HTMLElement` interface in JavaScript that represents the text content of an element. To replace this property with a `PropertyDescriptor`, you can define a getter and setter for it. Here's an example:
```javascript
const textPropertyDescriptor = Object.getOwnPropertyDescriptor(HTMLElement.prototype, 'innerText');
Object.defineProperty(HTMLElement.prototype, 'innerText', {
get() {
// your custom logic for getting the text content
return textPropertyDescriptor.get.call(this);
},
set(value) {
// your custom logic for setting the text content
textPropertyDescriptor.set.call(this, value);
}
});
```
In this example, we first retrieve the original `innerText` property descriptor using `Object.getOwnPropertyDescriptor`. Then, we define a new property descriptor for `innerText` using `Object.defineProperty`. The `get` and `set` functions are defined to handle getting and setting the text content, respectively. In each function, we call the corresponding method on the original property descriptor using `call(this)` to ensure that we don't break any existing functionality.
