Example 1: In this example, we are checking whether the given value is null or not by the use of the _isNull() method.
// 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.
// Requiring the lodash library
const _ = require("lodash");
// Use of _.isNull()
// method
let gfg = _.isNull(NaN);
// Printing the output
console.log(gfg);
Output:
false
