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 ofvalue
isnull
orundefined
.
