javascript-lodashHow do I use Lodash's isnil method in JavaScript?


The _.isNil() method in Lodash is used to check if a value is null or undefined. It returns true if the value is null or undefined, and false if it is any other value.

Here is an example of using _.isNil():

const _ = require('lodash');

const value = null;

console.log(_.isNil(value));
// output: true

In the example above, _.isNil() is used to check if the value of value is null or undefined. The output is true because the value of value is null.

The parts of the code are:

  • const _ = require('lodash');: This is used to import Lodash into the project.
  • const value = null: This is the value that is being checked.
  • console.log(_.isNil(value)): This is the call to the _.isNil() method, which is used to check if the value of value is null or undefined.
