i newbie angular js , way trying understand directive functionality written below

function mydirective($interpolate, $compile) { homecoming { restrict: 'e', scope: { mycontent: '=', myurls: '=', mydata: '@' }, replace: true, template: '<div ng-bind-html="html"></div>', link: function ($scope, element, attrs) { $scope.$watch('mycontent', function (value) { var html = $interpolate(value)($scope); element.html(html); $compile(element.contents())($scope); }); } } }

i not able understand next above.

1) $interpolate(value)($scope) ? sec argument $scope.

2) $compile function doing ?

3) div ng-bind-html="html" in template ?

what $interpolate(value)($scope) do?

gets literal value of value variable

what sec argument $scope.

it provides context data-binding

it('should interpolate undefined context', inject( function($interpolate) { expect($interpolate("hello, world!{{bloop}}")()).tobe("hello, world!") } ));

what $compile function doing?

it converts string angular markup

div ng-bind-html="html" in template do?

it compiles html string within $scope.html , adds markup

references

angularjs guide: scope watch depths

angularjs source: interpolatespec.js

angularjs look security internals

difference in $interpolate between angularjs 1.0 , 1.2
