We should form a "nice" function with names of steps. Similar to rambo it should keep track of functions it combines into a single one to give nice

const f = change(source, destination)
f.toString()
// copy "foo"
// trim "bar"

Version 1.7.0 has been published to NPM. The full release note can be found at change-by-example/releases/tag/v1.7.0.

Tip: safely upgrade dependency change-by-example in your project using next-update

const source = {
  name: 'john',
  age: '42',
  occupation: 'mechanic'
}
const destination = {
  name: 'John',
  age: 42
}
const change = require('change-by-example')
const t = change(source, destination)
console.log(t.toString())
/*
name: _.capitalize(name)
age: _.parseInt(age)
*/

Similarly, deep paths will be shown using dots

const input = {
  name: 'foo',
  other: {
    info: {
      age: '42'
    }
  }
}
const output = {
  name: {
    first: 'foo'
  },
  age: 42
}
const t = change(input, output)
console.log(t.toString())
/*
name.first: R.identity(name)
age: _.parseInt(other.info.age)
*/
