To show the first 5 elements from the array by using forEach loop, you can use if statement

const arrays = [1, 2, 4, 6, 7, 44, 5, 7, 6];

arrays.forEach(function(value, index, array) {

    if(index <= 4) {
        document.write(value + "<br>");
    }

});

Where parameters:

Index = The index of the current element.
Value = The value of the current element.
Array = The array of the current element.
