Last Updated : 03 Sep, 2024

Lodash _.isArray() method checks if the given value can be classified as an Array Value or not.

_.isArray(value);

• value: This parameter holds the value that needs to be Checked for an Array.

• This method returns a Boolean value.

Example 1: In this example, we are checking whether the given value is an array or not and print the result in the console by the use of the _.isArray() method.

// Defining Lodash variable
const _ = require('lodash');

let val = [1, 2, 3]

// Checking for an Array
console.log("The Value is Array : "
    + _.isArray(val)); 

Output:

The Value is Array : true

Example 2: In this example, we are checking whether the given value is an array or not and print the result in the console by the use of the _.isArray() method.

// Defining Lodash variable
const _ = require('lodash');

let val = "GeeksforGeeks"

// Checking for an Array
console.log("The Value is Array : "
    + _.isArray(val)); 

Output:

The Value is Array : false

Example 3: In this example, we are checking whether the given value is an array or not and print the result in the console by the use of the _.isArray() method.

// Defining Lodash variable
const _ = require('lodash');

let val = { 1: 1 }

// Checking for an Array
console.log("The Value is Array : "
    + _.isArray(val)); 

Output:

The Value is Array : false

Note: This will not work in normal JavaScript because it requires the lodash library to be installed.
