Why are we are the value property to the field?

I am confused why we are adding the value to field inside the conditional statement. thanks

if (field.value === "") { return true; } else { return false; }

The conditional doesn't change the field value, it only tests it. In this example it is testing to see if the value is empty (same as a string with no contents).

This example is primarily to illustrate the function of a conditional. In actual practice the result of the comparison could be returned directly without using a conditional:

    return field.value === "";
