Lodash _.isArrayLike() Method
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.
Syntax:
_.isArrayLike(value);
Parameter:
- value: This parameter holds the value that needs to be Checked for an Array-Like Value.
Return Value:
This method returns a Boolean value.
Example 1: In this example, the lodash _.isArrayLke() method returns true for an Array.
Javascript
// 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.
Javascript
// Defining Lodash variable const _ = require( 'lodash' ); let val = "w3wiki" ; // 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.
Javascript
// 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.
