The difference is set is used to store only keys while map is used to store key value pairs. For example consider in the problem of printing sorted distinct elements, we use set as there is value needed for a key.

Unlike object types such as Record, a Map can store any type of value including objects, functions, and other primitives. We can create a new Map instance using the Map constructor. let myMap = new Map<string, number>(); Then we can add, update or delete entries from the Map using its inbuilt methods.

We can initialize HashMap using the constructor in four different ways : HashMap() It is the default constructor with initial capacity 16 and load factor 0.75. ... HashMap(int initialCapacity) ... HashMap(int initial capacity, float loadFactor) ... HashMap(Map map)

A record is analogous to an Object in JavaScript with the exception that the Record is not an Object but a deeply immutable primitive value. Likewise, a Tuple is like an Array but is a deeply immutable primitive value.
