Watching a single property in an array in AngularJS

Posted on by Peter MorrisCategories:Uncategorised
A typescript example that converts the array’s property into a single string that can be watched.
        $scope.$watch(
            () => this.someArray.map(x => x.selected ? "1" : "0").join(""),
            (newValue, oldValue, scope) => this.onSelectionChanged(this.getSelectedItems()));
