Map is ES6 feature and have nothing to do with Angular 2. You can create it using
Map 是 ES6 特性,与 Angular 2 无关。您可以使用创建它
var map = new Map<string, string[]>();
map.set('key', ['a', 'b', 'c']);
map.get('key');
You also need to set "module": "es6" in your tsconfig.json or use es6-shims definitions.
您还需要在 tsconfig.json 中设置 "module": "es6" 或使用 es6-shims 定义。
