How to iterate over set elements with JavaScript?

To iterate over set elements with JavaScript, we can use the for-of loop.

For instance, we write

const a = new Set();
a.add("Hello");

for (const key of a) {
  console.log(key);
}

to create a set with the Set constructor.

We add an entry into it with add.

Then we use a for-of loop to loop through the entries of a.

We get the entry being looped through from key.

Conclusion
