Deep Diff
Function returning an object representing the difference between two objects. The function is immutable-compliant as it does not affect the arguments.
Installation
npm install -S return-deep-diff
Usage
const objOne = a: 1 b: c: 2 d: 3 e: 4 const objTwo = a: 1 b: c: 2 d: 30 f: 50 e: 40 console/*returns: { b: { d: 30 }, e: 40 }*/ console/*returns: { b: { d: 30 f: 50 }, e: 40 }*/
The two objects must share the exact same structure, which is defined by the first object. If a key is present in the second but not the first object, it will not be present in the diff object unless keepNewKeys
equals true
.
The function does not mutate neither the first nor the second object.
