How can i resolve 'typeerror: x is not a symbol nor a string' in ruby?

This error typically indicates that a method expected a symbol or string but received a different type.

Example:

hash = {name: "John", age: 30}
puts hash[30]

Solution:

hash = {name: "John", age: 30}
puts hash[:age]

Ensure you're using the correct type (symbol or string) as key when accessing hash values.
