예제
set() 사용하기
var myMap = new Map();
// Add new elements to the map
myMap.set('bar', 'foo');
myMap.set(1, 'foobar');
// Update an element in the map
myMap.set('bar', 'baz');
set() 체이닝
set()이 같은 Map을 반환하므로 메서드를 여러 번 연속해서 호출할 수 있습니다.
// Add new elements to the map with chaining.
myMap.set('bar', 'foo')
.set(1, 'foobar')
.set(2, 'baz');
