Small library who deeply check for difference between two objects
npm install return-deep-diffFunction returning an object representing the difference between two objects. The function is immutable-compliant as it does not affect the arguments.
``
npm install -S return-deep-diff
`js
import deepDiff from 'return-deep-diff'
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.log(deepDiff(objOne, objTwo))
/*
returns:
{
b: {
d: 30
},
e: 40
}
*/
console.log(deepDiff(objOne, objTwo, true))
/*
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.
