    We can do this by getting random item from each array and adding them to a new array. we are using the pick function get a random item each item.

    then we are using the for loop to create the final arrays.

    const pick = function(items) {
  return items[Math.floor(Math.random() * items.length)];
};

const array1 = ["Male", "Female"];
const array2 = [18,19,20];
const array3 = ["Self Employed", "Part Time", "Full Time"];

for (let index = 0; index < 10; index++) {
  var created_array = [];
  created_array.push(pick(array1));
  created_array.push(pick(array2));
  created_array.push(pick(array3));
  
  console.log(created_array);
}

    To pick one item from each of three arrays and create a new array in JavaScript, you can use a combination of array manipulation methods like Math.random() and push(). Here’s an example of how you can achieve this:
