<h2>Understanding Do-While Loops in JavaScript</h2>
<h3>What is a Do-While Loop?</h3>
A <strong>Do-While Loop</strong> is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. Unlike other loops, the Do-While loop ensures that the code block is executed <strong>at least once</strong> before the condition is tested. This makes it particularly useful in scenarios where the initial execution of the loop must occur regardless of the condition.
<h3>Syntax of Do-While Loop</h3>
The basic syntax of a Do-While loop in JavaScript is as follows:
<pre><code>
do {
// Code block to be executed
} while (condition);
|
Key Points: The do block contains the code that will be executed. After executing the code block, the while condition is evaluated. If the condition is true, the loop continues; if…
