Can you highlight the difference between these two code snippets?
function Ctrl($scope) {
$scope.$watch(function() {
return this.variable;
}.bind(this), /*...*/);
}
and
function Ctrl($scope) {
$scope.$watch(angular.bind(this, function() {
return this.variable;
}, /*...*/);
}
To me, they seem similar, but is there any particular advantage of using angular.bind?
In older browsers, like IE 8, the built-in Function.prototype.bind function is not available. However, you can achieve the same functionality using a polyfill. Angular.js also internally handles this by utilizing a similar approach.
Unlike Function.prototype.bind, the angular.bind function in Angular does not rely on it, making it potentially usable in older browsers. Nevertheless, compatibility with older browsers depends on the version of Angular being used.
