Hashes and Symbols
Many Paths to the Same Summit
Remember, there are always many ways of accomplishing something in Ruby. Converting strings to symbols is no different!
Besides using .to_sym
, you can also use .intern
. This will internalize the string into a symbol and works just like .to_sym
:
"hello".intern # ==> :hello
When you’re looking at someone else’s code, you might see .to_sym
or .intern
(or both!) when converting strings to symbols.
Instructions
1.
Update your code from the last exercise to use .intern
instead of .to_sym
.
