I wish this help you Other answers argue correctly that :"foo bar" is superior to "foo bar".to_sym because it is clearer, better expresses your intention, is more readable, faster etc. But there is one more reason: "foo bar".to_sym relies on String#to_sym method, and there is a possibility (although remote) that this method might be redefined. This is the one non-cosmetic reason why :"foo bar" is in principle better practice.

code :

I hope this helps you . To help you decide which hash literal syntax to use, check out:
Why using the hash rocket syntax is still sometimes necessary.
code :
# bad
hash = { 'one' => 1, 'two' => 2, 'three' => 3 }

# good
hash = { one: 1, two: 2, three: 3 }
# bad
hash = { :one => 1, :two => 2, :three => 3 }

# good
hash = { one: 1, two: 2, three: 3 }
# bad
{ a: 1, 'b' => 2 }

# good
{ :a => 1, 'b' => 2 }
