ProgramGuruTo create a Set of Sets in JavaScript, you can use nested Sets. You create individual sets and then add them to another set.
In this example,
set1, set2, and set3. We add the elements 1, 2, 3 to set1, 4, 5, 6 to set2, and 7, 8, 9 to set3.setOfSets and add set1, set2, and set3 to it. This nests the three sets within a single set.setOfSets using a for...of loop. Within the loop, we print each individual set to the standard output.let set1 = new Set([1, 2, 3]);
let set2 = new Set([4, 5, 6]);
let set3 = new Set([7, 8, 9]);
let setOfSets = new Set();
setOfSets.add(set1);
setOfSets.add(set2);
setOfSets.add(set3);
for (let set of setOfSets) {
console.log(set);
}Output:
Set(3) {1, 2, 3}
Set(3) {4, 5, 6}
Set(3) {7, 8, 9}In this example,
setA, setB, and setC. We add the elements "apple", "banana", "cherry" to setA, "dog", "elephant", "fox" to setB, and "grape", "honeydew", "kiwi" to setC.setOfStringSets and add setA, setB, and setC to it. This nests the three sets within a single set.setOfStringSets using a for...of loop. Within the loop, we print each individual set to the standard output.let setA = new Set(["apple", "banana", "cherry"]);
let setB = new Set(["dog", "elephant", "fox"]);
let setC = new Set(["grape", "honeydew", "kiwi"]);
let setOfStringSets = new Set();
setOfStringSets.add(setA);
setOfStringSets.add(setB);
setOfStringSets.add(setC);
for (let set of setOfStringSets) {
console.log(set);
}Output:
Set(3) {'apple', 'banana', 'cherry'}
Set(3) {'dog', 'elephant', 'fox'}
Set(3) {'grape', 'honeydew', 'kiwi'}In this tutorial, we learned How to create a Set of Sets in JavaScript language with well detailed examples.
