The while loop is a fundamental control structure in JavaScript that allows you to execute a block of code repeatedly as long as a specific condition is true. It is particularly useful when you need to perform an operation multiple times based on a dynamic condition.
In this article, we'll explore the mechanics of the while loop, dive into code examples, and discuss best practices for effective usage.
To begin, let’s examine the syntax of the while loop:
while (condition) {
// code block to be executed
}The condition is an expression that is evaluated before each iteration of the loop. If the condition is true, the code block inside the curly braces ({ }) is executed. This process continues until the condition becomes false.
Here’s a simple example that demonstrates the use of a while loop to print the numbers from 1 to 5:
let i = 1;
while (i <= 5) {
console.log(i);
i++;
}In this example, the loop initializes a variable i with a value of 1. The condition i <= 5 is checked before each iteration. As long as i is less than or equal to 5, the code block inside the loop is executed, printing the…
