## Overview
We can use the `delete(key)` method to delete an entry of a hash. It returns the associated value of the entry deleted.
## Syntax
```ruby
hash.delete(key)
```
## Parameters
`hash`: The hash we want to delete an entry from.
## Return value
This method returns the value of the entry deleted.
## Example
Let's look at the code below:


# create hashes
h1 = {one: 1, two: 2, three: 3}
h2 = {name: "okwudili", stack: "ruby"}
h3 = {"foo": 0, "bar": 1}

# delete some keys
# and print return values
puts h1.delete(:three)
puts h2.delete(:stack)
puts h3.delete(:bar)

# now print hashes
puts h1
puts h2
puts h3

# Explanation
* **Lines 2 to 4**: We create three hashes `h1`, `h2`, and `h3`.
* **Lines 8 to 10**: We invoke the `delete(key)` method on the hashes and print their returned values.
* **Lines 13 to 15**: We print the hashes after some entries are deleted.
