In JavaScript, create a function called onlyBooleans which is an array of elements and count only the boolean elements occurring in the array.

The output is the number of occurrences.

Example of the code:

function onlyBooleans (Myarray) {

// Insert code here;

}

onlyBooleans ([356, 8,"name",true, 7, true, "yes", true, false, false, true]);

Output: 6
