What is the difference between Map and Object in JavaScript?
An example of an AI chatbot conversation about the differences between Map and Object in JavaScript.
What is the difference between Map and Object in JavaScript?
In JavaScript, both Map and Object are used to store key-value pairs, but they have some key differences.
Can you explain those differences in detail?
Sure! Maps can have keys of any type, while Objects only accept strings and symbols as keys. Also, Maps maintain the order of insertion.
What about performance? Is one faster than the other?
Yes, Maps generally offer better performance for frequent additions and removals of key-value pairs compared to Objects.
Are there any use cases where I should prefer one over the other?
You should use Maps when you need ordered keys or non-string keys, and Objects when you need a simple structure for JSON-like data.
