## Overview
The `clear` method is used to clear all entries of a hash in Ruby. It removes all hash entries and returns the hash.
## Syntax
```ruby
hash.clear
```

## Return value
This method returns the hash itself.

## Example
Let's look at the code below:


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

# print all hashes
puts h1
puts h2
puts h3

# clear all hashes
h1.clear
h2.clear
h3.clear

# Reprint hashes
puts h1
puts h2
puts h3

## Explanation
* Lines 2 to 4: We create hashes `h1`, `h2`, and `h3` with some entries.
* Lines 7 to 9: We print all hashes to the console.
* Lines 12 to 14: We clear the entries of the hashes by using the `clear` method.
* Lines 17 to 19: We reprint the hashes (with cleared elements) to the console.

When we run the code, the hash entries are cleared using the `clear` method.
