Let's initiate our journey with Sets. In TypeScript, a Set is a unique type of object that stores diverse data types, be they primitive or object variables. A Set does not contain duplicates. Imagine a Set as a special bag holding unique treasures (elements), ensuring that each remains exclusive.

The array houses duplicates, whereas the set displays only unique values.

In TypeScript, the creation of a Set leverages the new keyword alongside the Set() constructor. A distinctive feature of using Set in TypeScript is the ability to specify the type of elements it holds through generics. This is done by adding <type> next to Set, where type is the data type of the elements. This practice ensures type safety, allowing only elements of the specified type to be added to the .
