how to iterate through a map code example

Example 1: iterate map

Map map = ...
for (Map.Entry entry : map.entrySet()) {
    System.out.println(entry.getKey() + "/" + entry.getValue());
}

Example 2: loop through map in js

var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

for (const [key, value] of myMap.entries()) {
  console.log(key, value);
}

Example 3: iterate through map

//traditional way (long)
for(map::iterator it=m.begin(); it!=m.end(); ++it)
	if(it->second)cout<first<<" ";
//easy way(short) just works with c++11 or later versions
for(auto &x:m)
	if(x.second)cout<

var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

for (const [key, value] of Object.entries(myMap)) {
  console.log(key, value);
}
