The **`findByIdAndDelete()`** is a function in Mongoose used to find a document by the `_id` field and then remove the document from the collection.

It returns the document removed or deleted.

#   
## Syntax
```js
Model.findByIdAndDelete(id)
```

## Parameters
`id`: This is the `id` value. It is this value that is checked among all the documents by comparing their `_id` fields. If the document is found, then it is removed.

## Return value
The deleted document is returned. 

## Example 
In the example below, a Mongoose Schema was created, then the function `findByIdandDelete()` is called to delete a document in the collection.



// import mongoose
const mongoose = require("mongoose");

// creating a Schema with mongoose
let Product = mongoose.model("Product", new mongoose.Schema({
    name: String,
    price: Number
  })
)

// find a document with id
let id = "60ff9d6fa676bb1334686840"

// find and delete document with the id
let product = await Product.findByIdAndDelete(id)

console.log(product)

/*  OUTPUT
    {name: "Pizza": price: 300}
*/

In the code above, the document with id `60ff9d6fa676bb1334686840` is deleted. Then, it is returned as `{name: "Pizza", price: 300}`
