An example of an AI chatbot conversation about JavaScript collections and their usage.
What are JavaScript collections and how do they work?
JavaScript collections refer to data structures like Arrays, Sets, and Maps that store multiple values. They help manage data efficiently.
Can you explain the difference between an Array and a Set?
Sure! An Array is an ordered list of values, allowing duplicates, while a Set is an unordered collection of unique values.
When should I use a Map instead of an Object?
Use a Map when you need key-value pairs with any type of keys and maintain the order of entries. Objects are limited to strings as keys.
What are some common methods for manipulating Arrays?
Common methods include push(), pop(), shift(), unshift(), map(), filter(), and reduce(). They help in adding, removing, and transforming elements.
