In JavaScript, the Set is a built-in collection that allows you to store unique values of any type, Set can store any type of value whether primitive or objects. It provides methods for adding, removing, and querying elements in an efficient way.
let s = new Set(["a", "b", "c"]);
console.log(s);
let s = new Set(["a", "b", "c"]);
console.log(s);
Output
Set(3) { 'a', 'b', 'c' }
Set Basics Examples
- Set vs Map
- How to iterate over Set?
- Union of two Sets
- Intersection of two sets
- Element Ordering in a Set
- Sort a Set
- Array to Set
- map, reduce and filter a Set
- Set.clear() vs Set.delete()
- Difference between Two Sets
Coding Problems Based on Set
Set internally uses hashing. Therefore the problems that require quick search, insert and/or delete operations can be efficiently solved using set.
