How To Iterate Over A Map In JavaScript

To iterate through the elements in a JavaScript Map(), you can forEach. It will call the function you pass as the argument and will pass the value as the first parameter, and the key as the second parameter.

const someMap = new Map();
someMap.set("cat", "meow");
someMap.set("dog", "bark");
someMap.set("fish", "gurgle(?)");

someMap.forEach((value, key) => {
  console.log({ key, value });
});
