## Overview
##  What is a loop?
A **`loop`** repeatedly executes a code block until a condition is satisfied.
###
### What is a `while` loop in Clojure?

A Clojure **`while`** loop evaluates a conditional expression and if the condition returns `true`, it executes the codes in the `do` block until the conditional expression returns `false`.





#       
#  Syntax
```
(while(expression)
   (do
      codeblock))
```

## Code example

(ns clojure.examples.hello
   (:gen-class))

;; This program displays Hello World
(defn looping []
   (def y (atom 1))
   (while ( < @y 9 )
      (do
         (println @y)
         (swap! y inc))))
(looping)

#        
## Code explanation
* Line 5: We create a function to demonstrate the `while` loop.

* Line 6: We define a variable `y` with the `atom` keyword, so that the variable can be changed.

* Line 7: We declare the `while` loop with a condition that will continue running as long as `y` is less than 9.

* Line 8: The `do` block is used to identify the code that will be repeated.

* Line 9: We print the value of `y`.

* Line 10: We use `swap!` to populate the changed values of `y`.

* Line 11: We call the `looping` function that we created earlier.




The while loop in Clojure

A Clojure while loop executes a code block repeatedly while a condition is true, using the syntax `(while(cond) (do codeblock))`.
