While reading a book on Angular.js, I came across the following syntax:
$scope.selectedOrder; // What does this syntax mean?
$scope.selectOrder = function(order) {
$scope.selectedOrder = order;
};
I understand that selectedOrder is a property of the $scope object.
However, I am puzzled about the purpose of "$scope.selectedOrder;". It doesn't seem to perform any operations. Can someone provide me with a hint? Thank you.
On occasion, I implement this particular pattern.
Take for example a situation where you have a "class":
function Vehicle() {
var $scope = this;
$scope.tyres; // Public property
$scope.setTyres = function(num) {
$scope.tyres = num;
}
}
var vehicle = new Vehicle();
vehicle.setTyres(3);
console.log("Number of tyres", vehicle.tyres)
In this scenario, the aim is to make the tyres accessible publicly. By declaring it outside of the setTyres function, developers can easily identify what is public rather than having it concealed within the function itself.
