Lodash _.invert() method is used to return the copy of an object where the object key is converted into value and object value is converted into the key. If the object contains duplicate values, subsequent values overwrite property assignments.
Syntax:
_.invert(object);
Parameters:
- object: This parameter holds the object to invert.
Return Value:
This method returns the new inverted object.
Example 1: In this example, we are inverting the given object with the help of the lodash _.invert() method.
Javascript
const _ = require("lodash");
let obj = { 'a': 1, 'b': 2, 'c': 3 };
console.log(_.invert(obj));
|
Output:
{ '1': 'a', '2': 'b', '3': 'c'}
Example 2: In this example, we are inverting the given object with the help of the lodash _.invert() method. as b and c both have the same value that’s why it will only add the last key which is c.

console.log(_.invert(obj));
