Comparing the properties of objects

Question

Comparing the properties of objects

When dealing with multiple users' settings, it is important to find the intersection of their boolean values. This involves comparing their setting objects to determine if a specific setting is true for some users and false for others. For example, selecting multiple users with different settings may result in an indeterminate status display.

I have come up with an example solution so far, but I am open to any suggestions on how to improve the process. Check out my progress here: http://jsfiddle.net/kT7UP/

Thank you in advance for your input.

Answer №1

To avoid repetition, consider creating a reusable function for testing each property by passing in the property name as an argument. This way, you can simplify your code and make it more maintainable. Here's an example of how you can refactor your current code:

function testProperty(prop) {
    for (var i = 0; i < users.length; i++) {
        if (users[i][prop] !== model[prop]) {
            console.log('Indeterminate status');
            return false;
        }
    }
    return true;
}

testProperty("Printing");
testProperty("Sharing");
testProperty("Reading");
testProperty("AccountEnabled");
testProperty("Fax");

Remember the coding principle DRY (don't repeat yourself). If you notice repetitive code blocks with minor variations, it's a sign that you should abstract those into reusable functions to promote code reusability instead of duplicating the same logic in multiple places.
