Looping Programs

The provided JavaScript snippets cover a variety of basic programming tasks and operations. Here's a summary and explanation for each:

1. Prime Numbers

Code:

javascript
 
1for (let i = 2; i <= 100; i++) {
2    let isPrime = true;
3    for (let j = 2; j < i; j++) {
4        if (i % j === 0) {
5            isPrime = false;
6            break;
7        }
8    }
9    if (isPrime) console.log(i);
10}

Explanation: This code prints all prime numbers between 2 and 100. It checks each number i to see if it's divisible by any number j from 2 up to i-1. If a divisor is found, the number is not prime.

2. Fibonacci Sequence

Code:

javascript
 
1let n = 10;
2let a = 0, b = 1;
3
4for (let i = 0; i < n; i++) {
5    console.log(a);
6    let temp = a + b;
7    a = b;
8    b = temp;
9}
