The identity transformer, IdentityT, transforms a monad to itself. The base type, Identity, wraps a simple value.

# To use as standalone package
$ npm install --save akh.identity

# To use as part of akh library
$ npm install --save akh

Usage

The Identity and IdentityT implement the Fantasy Land monad, functor, and applicative functor interfaces.

// Identity monad
require('akh.identity').Identity
require('akh').Identity

// Identity monad transformer
require('akh.identity').IdentityT
require('akh').IdentityT

Identity.run(m), m.run()

Extract a value from an identity monad.

IdentityT.run(t), t.run()

Same as Identity.run but for transformed type.
