How to create a Set of Sets in TypeScript


How to create a Set of Sets in TypeScript ?

Answer

To create a Set of Sets in TypeScript, you can use nested Sets. You create individual sets and then add them to another set.



✐ Examples

1 Creating a Set of Sets of Integers

In this example,

  1. First, we create three individual sets of integers named set1, set2, and set3. We add the elements 1, 2, 3 to set1, 4, 5, 6 to set2, and 7, 8, 9 to set3.
  2. Next, we create a set named setOfSets and add set1, set2, and set3 to it. This nests the three sets within a single set.
  3. We then iterate over each set within setOfSets using a for...of loop. Within the loop, we print each individual set to the standard output.

TypeScript Program

let set1: Set<number> = new Set([1, 2, 3]);
let set2: Set<number> = new Set([4, 5, 6]);
let set3: Set<number> = new Set([7, 8, 9]);

let setOfSets: Set<Set<number>> = new Set();
setOfSets.add(set1);
setOfSets.add(set2);
setOfSets.add(set3);

for (let set of setOfSets) {
    console.log(set);
}

Output

Output:
Set(3) {1, 2, 3}
Set(3) {4, 5, 6}
Set(3) {7, 8, 9}

2 Creating a Set of Sets of Strings

In this example,

  1. First, we create three individual sets of strings named setA, setB, and setC. We add the elements "apple", "banana", "cherry" to setA, "dog", "elephant", "fox" to setB, and "grape", "honeydew", "kiwi" to setC.
  2. Next, we create a set named setOfStringSets and add setA, setB, and setC to it. This nests the three sets within a single set.
  3. We then iterate over each set within setOfStringSets using a for...of loop. Within the loop, we print each individual set to the standard output.

TypeScript Program

let setA: Set<string> = new Set(["apple", "banana", "cherry"]);
let setB: Set<string> = new Set(["dog", "elephant", "fox"]);
let setC: Set<string> = new Set(["grape", "honeydew", "kiwi"]);

let setOfStringSets: Set<Set<string>> = new Set();
setOfStringSets.add(setA);
setOfStringSets.add(setB);
setOfStringSets.add(setC);

for (let set of setOfStringSets) {
    console.log(set);
}

Output

Output:
Set(3) {'apple', 'banana', 'cherry'}
Set(3) {'dog', 'elephant', 'fox'}
Set(3) {'grape', 'honeydew', 'kiwi'}
