    for (var key in myObject) {
    if (myObject.hasOwnProperty(key)) {
    myObject[key] *= 2;
    }
    }

    console.log(myObject);
    // { 'a': 2, 'b': 4, 'c': 6 }

    What type of key can a JavaScript map use?
    Any type of key is possible. Although map[key] also works, e.g. we can set map[key] = 2, this is treating map as a plain JavaScript object, so it implies all corresponding limitations (only string/symbol keys and so on). So we should use map methods: set, get and so on. Map can also use objects as keys.
