How do you compare Object and Map?

1) Keys:
Objects: Keys are limited to Strings and Symbols.
Maps: Keys can be any value, including functions, objects, and primitives.

2) Order:

Objects: Keys have no guaranteed order.
Maps: Keys are ordered based on insertion sequence.

3) Size:
Objects: Size must be determined manually.
Maps: Size can be easily obtained using the size property.

4) Iteration:
Objects: Require manual key extraction for iteration.
Maps: Are directly iterable.

5) Prototype:
Objects: Have a prototype, which may lead to unintended key collisions.
Maps: Provide a clean alternative without a prototype.


Performance:

6) Maps: May perform better in scenarios involving frequent addition and removal of key-value pairs.

In conclusion, Maps offer more flexibility, ordering, and ease of use, especially for scenarios involving iteration and frequent modifications.

One Step ahead of the best✊
