ng-app 앵귤러를 사용하겠다는 의미

위 방식처럼 사용하기보단 view부분과 data부분을 분리해서 사용한다
index.html

script.js의 app을 기반으로 module을 선언한다 (ng-app에 script의 모듈이 들어간다)
ng-controller를 통해 $scope를 지정하고
기본적인 데이터및 함수들을 정의할수 있다
script.js
//모듈: 컨테이너
//모듈안에: 컨트롤러, 디렉티브, 서비스가 담겨있다
(function () {
// app이라는 변수에 todo라는 모듈이 담긴다
var app = angular.module("todo", []);
//두번째 파라미터는 배열로준다
app.controller("TodoCtrl", [
"$scope",
function ($scope) {
// $scope.name = "Chris";
// $scope.data = "aa";
$scope.todo = {
title: "요가 수련",
completed: false,
createdAt: Date.now(),
};
},
]);
})();
angular는 vue와 같이 양방향 바인딩을 지원한다
ng-model=todo.title을 통해 값을 변경하면 자연스럽게 todo.title이 변경된다
v-model과 비슷한 개념인거같다.
