An example of an AI chatbot conversation about when to use symbols in Ruby.
When should I use symbols in Ruby?
You should use symbols in Ruby when you need a lightweight, immutable identifier, like keys in hashes.
Can you give me an example of using symbols in a hash?
Sure! Here's an example: my_hash = { name: 'Alice', age: 30 } where :name and :age are symbols.
What are the benefits of using symbols over strings?
Symbols are more memory-efficient than strings because they are immutable and reused in memory.
Are there any situations where I should avoid using symbols?
Yes, avoid using symbols when you need mutable objects or when the data is dynamic and changes frequently.
