JS print all prime numbers

Comment

// program to print prime numbers between the two numbers

// take input from the user
const lowerNumber = parseInt(prompt('Enter lower number: '));
const higherNumber = parseInt(prompt('Enter higher number: '));

console.log(`The prime numbers between ${lowerNumber} and ${higherNumber} are:`);

// looping from lowerNumber to higherNumber
for (let i = lowerNumber; i <= higherNumber; i++) {
    let flag = 0;

    // looping through 2 to user input number
    for (let j = 2; j < i; j++) {
        if (i % j == 0) {
            flag = 1;
            break;
        }
    }

    // if number greater than 1 and not divisible by other numbers
    if (i > 1 && flag == 0) {
        console.log(i);
    }
}

write a javascript program to find prime numbers?

Comment

// This program will use a loop to check if a number is prime.

// To start, set a flag to true
let isPrime = true;

// We will use a for loop to loop through numbers from 2 to the number we are testing
// We can start at 2 because all numbers are divisible by 1
const numToTest = 17;
for(let i = 2; i < numToTest; i++) {
  
  // If the number is divisible by any other number (besides 1 and itself)
  // then it is not a prime number
  if(numToTest % i === 0) {
    isPrime = false;
    break;
  }
}

// Finally, output the result
if(numToTest == 1) { console.log(`${numToTest} is not a prime number`);}
  
else if (isPrime) {
  console.log(`${numToTest} is a prime number`);
} else {
    console.log(`${numToTest} is not a prime number`); }
