ES6 Maps

The video tutorial introduces maps in ECMAScript 6, explaining their structure as key-value pairs. It demonstrates creating maps, setting keys and values, and retrieving values using the get method. The tutorial covers iterating through maps using 'for of' and 'forEach' loops, and converting maps to arrays. The video concludes with a brief mention of sets, another new object type in ES6.
