Lodash _.isArrayLike() Method - GeeksforGeeks

Last Updated : 03 Sep, 2024

Lodash _.isArrayLike() method checks if the value is Array-like. A value is considered array-like if it's not a function and has a value.length that's an integer greater than or equal to 0 and less than or equal to Number.MAX_SAFE_INTEGER.

_.isArrayLike(value);

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

• This method returns a Boolean value.

Example 1: In this example, the lodash _.isArrayLke() method returns true for an Array.

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

let val = [1, 2, 3]

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

Output:

The Value is ArrayLike : true

Example 2: In this example, the lodash _.isArrayLke() method returns true for strings as their length can be calculated.

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

let val = "GeeksforGeeks";

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

Output:

The Value is ArrayLike : true

Example 3: In this example, the lodash _.isArrayLke() method returns false.

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

let val = { 1: 1 };

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

Output:

The Value is ArrayLike : false

Note: This will not work in normal JavaScript because it requires the lodash library to be installed and can be installed using npm install lodash.
