In #javascript falsy values are false, 0, ” ", null, NaN, undefined. Now we can find out how to remove this kind of value from our array. To achieve this, we are going to use the .filter().🚀

Sometimes we need to select a value from the array randomly. To create it, we can get a random index number according to the array length.🚀

Shuffling is easy with the sort method. As long as it returns a random number, positive or negative, we can sort it with a random order.🚀

We can use a Set() to ensure that values in the array we are checking are not duplicated, and we will use .filter and .includes methods. As a result, we will get the array with values that were presented in both arrays.🚀
