#API Overview

Functions - API calls offered directly by the extension


Signature	`cp.fn.prop.mutate(getFn[, setFn]) -> function(prop) -> cp.prop`
Type	Function
Description	A function combinator which returns a function that receives a cp.prop and creates a mutated `cp.prop` based on the `getFn` and `setFn` provided.
Parameters	getFn - A function that receives the current value and returns the modified value of the prop. setFn - (optional) A function that receives the modified value, along with the current value of the prop and returns a original value of the prop.
Returns	A cp.prop that is the result of the mutation.
Notes	Unlike `cp.prop:mutate(...)`, the `getFn` receives the actual current value when called, rather than the `cp.prop` itself, and no additional parameters. Also unlike `cp.prop:mutate(...)`, the `setFn` is called with the mutated value and the current value, rather than the `cp.prop` itself, and no additional parameters.
Examples	None
