Array.filter is not working properly

Question

I have an array and I want to remove the entry from it. I use Array.filter() , but it returns the same array as it.

My code is:

 var url = window.location.pathname, orderId = url.split('/').slice(-2)[0]; var Cart = JSON.parse(localStorage.getItem('Cart')); newCart=Cart.filter(function(item) { if (parseInt(item.orderId) == parseInt(orderId)) { return {}; } else { return item; } }); localStorage.setItem('Cart',JSON.stringify(newCart)); 

Answer 1

You need to return true or false to the filter to filter the data from the array, return true to save the element, otherwise false. This way you can do something like this using filter()

 newCart = Cart.filter(function(item) { return parseInt(item.orderId, 10) != parseInt(orderId, 10); });
