Create functions for use with functional methods like map
, reduce
,
filter
, etc. that get object properties without need of anonymous wrappers.

See Components

Sorry for namespaced package, all good names taken.
Examples
Before:
Horrible anonymous wrapper is required to map the length
property.
'apple' 'banana' 'pineapple'// => [5, 6, 9]
After
Wow. Much cleaner.
'apple' 'banana' 'pineapple'// => [5, 6, 9]
get
to evaluate methods
Use // Calls the 'italics' method on each supplied item'apple' 'banana' 'pineapple'// => ['<i>apple</i>', '<i>banana</i>', '<i>pineapple</i>']
get
to evaluate methods, passing in arguments
Use // Calls the 'substr' method, passing in arguments'apple' 'banana' 'pineapple'// => ['a', 'b', 'p']
Convoluted Description:
Takes a property name, prop
along with any number of additional
arguments, and returns a function, that takes an object of any type, and
returns the value of prop
on that object. If prop
is a method, the
returned value with be the result of evaluating that method, passing in
the the additional arguments.
Turns out this is hard to describe.
