Easiest way to check if a variable is an array in Javascript

The simplest way to verify if a variable is an array in JavaScript is to use the 'instanceof' operator. This method checks the variable's instance type versus the Array constructor.

In practical examples, using 'instanceof Array' allows you to easily determine the type of the variable. For example, a string will return false, confirming it’s not an array.

You can create a reusable function called 'ismyvararray' that takes a variable as an argument and returns a boolean, indicating whether it is an array.

This technique enhances the clarity of your code by providing a straightforward method to check variable types, preventing bugs due to type mismatches.
