Currently going through Grokking algorithms and it defines hashmap as key/value pairs but isn't that the same as object are they the same thing or what's the difference between the two

Just see objects as a group of variables that are related together with methods to work on them. That’s the foundation of object oriented programming . Hash maps are just like array but with named indexes. I think javascript objects acts like hash maps and also like objects ( in the real sense of objects ie a group of related variables and functions to manipulate them).

You can google objects in programming in general to understand more.

You'll later give up and I'll be here waiting for you when that eventually happens rubbish..

In OOP objects are not key/value pairs . It is JavaScript that give you that impression.

Any key/value pair is a Map. we have different types of Map

TreeMap
HashMap
LinkedHashMap

oh, okay thanks i still got a lot to learn

Well in a HashMap your keys are unique. Except maybe you using a multimap data structure. This is one of the reason we ask people to start with Languages like C++ or Java, this is because this are Strongly and statically typed languages.

You can't have double key types in a JavaScript object still.

It's good to note that javascript has a map object, which works very similar to the hashmaps in Java for example.

Yeah ES6. Map and Sets

It would complain but allow it

It won't. It reassigns what you had on the previous key to the present.

Hmm but that is not a good Idea it leaves room for error.
