How to use pickBy Function In Lodash

Using omitBy and isNull Functions

In this approach, we are using Lodash’s pickBy function with _.identity as the predicate to create a new object with properties that are not null, removing null values and producing the cleaned result.

Example: The below example uses the pickBy function to Remove a null from an Object in Lodash.

JavaScript 
const _ = require('lodash');
let data = {
    name: 'GFG',
    age: null,
    city: 'Noida',
    country: null
};
let res = _.pickBy(data, _.identity);
console.log(res);

Output:

{ name: 'GFG', city: 'Noida' }
