What is the difference between symbols and strings in Ruby?
An example of an AI chatbot conversation about Ruby symbols and strings.
What is the difference between symbols and strings in Ruby?
In Ruby, symbols are immutable and unique identifiers, while strings are mutable and can be modified.
Can you give me an example of when to use a symbol instead of a string?
Sure! Use symbols for keys in hashes for better performance, as they are more memory efficient.
Are there any performance differences between using symbols and strings?
Yes, symbols are faster and consume less memory since they are stored only once, while strings can be duplicated.
What happens if I try to modify a symbol?
You can't modify a symbol because they are immutable. Attempting to do so will result in an error.
