Def foo a o b bar.
Ruby if then shorthand.
This code is functionally equivalent and perhaps a bit easier to understand.
It makes it easier to write correct forwarding code.
Thus thus case expr0 when expr1 expr2 stmt1 when expr3 expr4 stmt2 else stmt3 end.
If you don t this right you won t get the expected results.
If i is greater than 10 the if statement itself will evaluate to the string greater than or will evaluate to the string less than or equal to this is the same thing that the ternary operator is doing only the ternary operator is more compact.
Assuming there s no technical limitation or ambiguities i suggest that the shorthand syntax for symbol s in the context of an array be applied to strings also.
Until then keep sniffin out those code smells my friends.
Given an array of strings you could go over every string make every character uppercase.
One equals sign in ruby means assignment make sure to use when you want to find out if two things are the same.
Or if you have a list of user objects.
A when statement s expression is separated from code by the reserved word then a newline or a semicolon.
You could convert them into a list of their corresponding email addresses phone number or any other attribute defined on the user class.
Hi in message re.
Unpacking ampersand to proc.
Puts santa s on his way if today christmaseve if else.
But when you want to check for the opposite not true false.
Code smells and ruby shorthand.
If rubyists must be told they have to change their forwarding code.
I used def foo because that s currently valid ruby code but i m fine with any syntax.
Puts santa s on his way.

With an if statement you can check if something is true.
The ampersand can be used with an iterator like map and will call to proc on whatever symbol you pass it unless you pass it a block explicitly.
Map is a ruby method that you can use with arrays hashes ranges.
Foo a o b.
I often use group by x x and find x x the latter is to find the first item in an array which is true.
The main use for map is to transform data.
If today christmaseve puts santa s on his way else puts snow end shorthand.
It s like the no parentheses super shorthand but for any method.
Def foo bar.
What about using this.
