Javascript loop an array to find numbers divisible by 3

Javascript loop an array to find numbers divisible by 3

You can loop through an array in JavaScript using various methods such as a for loop, forEach method, or for...of loop, and then check each element to see if it's divisible by 3. Here's how you can do it using a forEach loop:

// Example array const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // Array to store numbers divisible by 3 const divisibleBy3 = []; // Loop through the array using forEach numbers.forEach(number => { if (number % 3 === 0) { divisibleBy3.push(number); } }); // Print the numbers divisible by 3 console.log("Numbers divisible by 3:", divisibleBy3);

This code will output:

Numbers divisible by 3: [3, 6, 9]

In this example:

  • We define an array numbers containing some numbers.
  • We initialize an empty array divisibleBy3 to store numbers divisible by 3.
  • We loop through the numbers array using the forEach method.
  • For each element in the array, we check if it's divisible by 3 using the modulo operator %. If the remainder is 0, it means the number is divisible by 3, so we push it into the divisibleBy3 array.
  • Finally, we print the numbers in the divisibleBy3 array.
