The isPrime function checks if a number is prime, while printPrimeNumbers generates an array of numbers from 1 to n, filters out non-prime numbers, and prints the prime numbers. JavaScript.
8 cze 2023 · A number is called prime if that number is divisible by 1 and the number itself. For example, 2, 3, 5, 7 , etc. are prime numbers. In this post, I will show you how to check if a number is prime or not in JavaScript with examples.
24 mar 2023 · The simplest method to identify prime numbers is to check each element of the array one by one using a for loop. Here's how you can do it: function isPrime(num) { if(num < 2) return false; for(let i = 2; i < num; i++) if(num % i === 0) return false; return true; } let arr = [2, 3, 4, 5, 6, 7, 8, 9, 10]; let primes = [];
