Lodash _.isNull() method is used to find whether the value of the object is null. If the value is null then returns true otherwise it returns false.

Syntax:

_.isNull(value);

value: This parameter holds the value to check.

Return Value:

This method returns true if the value is null, else false.

Example 1: In this example, we are checking whether the given value is null or not by the use of the _isNull() method.

JavaScript

// Requiring the lodash library  
const _ = require("lodash");

// Use of _.isNull()  
// method 
let gfg = _.isNull(null);
let gfg1 = _.isNull(void 0);

// Printing the output  
console.log(gfg);
console.log(gfg1);

Output:

true
false

Example 2: In this example, we are checking whether the 'NaN' is null or not by the use of the _isNull() method.

JavaScript

// Requiring the lodash library  
const _ = require("lodash");

// Use of _.isNull()  
// method 
let gfg = _.isNull(NaN);

// Printing the output  
console.log(gfg);

Output:
