json-line-diff

diff json side-by-side. (based on json-diff)

usage:

``js
import { diff } from 'json-line-diff';

const json1 = {
num: 1,
removed: true,
arr: [1, 2, 3],
};

const json2 = {
num: 2,
added: true,
arr: [2, 3],
};

console.log(diff(json1, json2));
`

output:

`

{ value: '{', line: 0, removed: false, path: '' },
{
value: ' "removed": true,',
