Accessing JSON keys#5810

I want to access and edit a nested key in the json, not the value. I tried unsetting the key value pair and setting a new pair with the key changed but this will add the new pair to the end of the json, i want to preserver the order of the json.

Is this supported?

Yes, Lodash provides methods to manipulate nested keys in an object while preserving the order. One approach is to use the _.unset() function to remove the nested key, and then use the _.set() function to set a new value with the desired key in the same position.

Here's an example:

const _ = require('lodash');// Sample JSON objectconst json = {  level1: {    level2: {      key1: 'value1',      key2: 'value2'    }  }};// Remove the nested key_.unset(json, 'level1.level2.key1');// Set a new value with the desired key at the same position_.set(json, 'level1.level2.newKey', 'newValue');console.log(json);

which will output

{  level1: {    level2: {      key2: 'value2',      newKey: 'newValue'    }  }}
