composeWith (
null.null.null.functions:...Function
) : Function

Performs right-to-left function composition using transforming function. The last argument may have any arity; the remaining arguments must be unary.

Note: The result of compose is not automatically curried. Transforming function is not used on the last argument.

Example
const composeWhileNotNil = R.composeWith((f, res) => R.isNil(res) ? res : f(res));

     composeWhileNotNil([R.inc, R.prop('age')])({age: 1}) //=> 2
     composeWhileNotNil([R.inc, R.prop('age')])({}) //=> undefined
Argument
