Entry Controlled Loop in JavaScript

Below is the implementation of Entry Controlled Loop in Javascript:

JavaScript
// Entry controlled loop using while loop
console.log("Entry controlled loop using while loop:");
let i = 0;
while (i < 5) {
    console.log(i);
    i++;
}
console.log();

// Reset i for the next loop
i = 0;

// Entry controlled loop using for loop
console.log("Entry controlled loop using for loop:");
for (let i = 0; i < 5; i++) {
    console.log(i);
}
console.log();

Output
Entry controlled loop using while loop:
0
1
2
3
4

Entry controlled loop using for loop:
0
1
2
3
4

Entry Controlled Loops in Programming

Entry controlled loops in programming languages allow repetitive execution of a block of code based on a condition that is checked before entering the loop. In this article, we will learn about entry controlled loops, their types, syntax, and usage across various popular programming languages.

What are Entry Controlled Loops?

Entry controlled loops are loop structures where the condition is checked before entering the loop body. If the condition evaluates to true, the loop body is executed, otherwise, the loop is terminated. Entry Controlled Loops are executed in the following order:...

Comparison with Exit-Controlled Loops

In contrast, exit-controlled loops (like the do-while loop) evaluate the condition after the loop body executes, ensuring the loop body runs at least once regardless of the condition.Understanding entry-controlled loops is essential for writing effective and efficient code, as they provide a structured way to repeat operations while maintaining control over the conditions for repetition....
