My list looks like this:
let chats: Chats[] = [
{id: 1, name: "James Anderson",read=false},
{id: 2, name: "James Anderson",read=true},
{id: 3, name: "James Anderson",read=true},
{id: 4, name: "James Anderson",read=true},
]
On my cshtml page, I have been using {{chats.length}} to get the total count. However, I now need to retrieve the count where the read value is set as false.
Therefore, I expect the count to be 1 instead of 4.
To check the number of unread messages in an array, you can utilize the array.filter method along with length property like so:
let result = chats.filter(t => !t.read).length;
EXAMPLE
var chats = [
{id: 1, name: "James Anderson", read: false},
{id: 2, name: "James Anderson", read: true},
{id: 3, name: "James Anderson", read: true},
{id: 4, name: "James Anderson", read: true}
];
let result = chats.filter(t => !t.read).length;
console.log(result);
