def [](object, opts = nil)
opts ||= {}.freeze
if object.is_a?(String)
return JSON.parse(object, **opts)
elsif object.respond_to?(:to_str)
str = object.to_str
if str.is_a?(String)
return JSON.parse(str, **opts)
end
end
JSON.generate(object, opts)
end
If object is a String, calls JSON.parse with object and opts (see method parse):
Example
json = '[0, 1, null]' JSON[json]# => [0, 1, nil]
Otherwise, calls JSON.generate with object and opts (see method generate):
Example
ruby = [0, 1, nil] JSON[ruby] # => '[0,1,null]'
