"downcase", "upcase", "capitalize", etc.

"downcase", "lowercase", "lowcase", "upcase", "uppercase", "capitalize", "snakecase", "snake_case", "trim", "strip"

downcase 'HELLO'           # => 'hello'
'HELLO'; downcase _        # => 'hello'
'HELLO'; downcase 'WORLD'  # => 'world'
# ...
downcase 'WORLD'            # => 'world'
downcase 'WORLD' cap: true  # => 'World'
# ...
capitalize 'hello world'  # => 'Hello World'

The cap: attribute, when set to something trueish, will make sure the resulting string(s) first char is capitalized. Not that "capitalize" itself will capitalize all the words (unlike Ruby's String#capitalize).

objects and arrays

Please note:

[ "A" "BC" "D" ]; downcase _    # => [ 'a' 'bc' 'd' ]
{ a: "A" b: "BC" }; downcase _  # => { a: 'a', b: 'bc' }
