The **`delete`** method of the map object is used to remove an entry associated with a passed key. 

# Syntax 

```py
mapObj.delete(key);
```

# Parameter

**`key`**: the key of the entry to be deleted from the map.

# Return value

The `delete` method returns `true` if there is an entry for the passed key and returns `false` otherwise.

# Code 

let map = new Map();

map.set(1, "one");
map.set(2, "two");

console.log("The map is ", map);
console.log("Removing the key 1 : ", map.delete(1));

console.log("The map is ", map);

console.log("Removing the key 3 : ", map.delete(3));
console.log("The map is ", map);

## Explanation
In the code above:

* We created a map object with two entries.

* We then called the `delete` method for the key `1`. The key `1` is present. So the entry is removed from the map and `true` is returned.

* We called the `delete` method for the key `3`. The key `3` is not present so `false` is returned.
