how to use the isdate function from the underscore library in javascript

To use the isDate function from the Underscore library in JavaScript, you first need to include the Underscore library in your code. You can do this by adding the following tag to your HTML file:

<script src="underscore.js"></script>
38 chars
2 lines

Once you have included the Underscore library, you can use the isDate function to validate whether a given value is a date object or not. Here is an example:

index.tsx
var date1 = new Date();
var date2 = "January 10, 2020";

console.log(_.isDate(date1)); //true
console.log(_.isDate(date2)); //false
132 chars
6 lines

In this example, we declare two variables, date1 and date2. date1 is a date object, while date2 is a string. We then use the _.isDate function to check whether each variable is a date object or not. The first call to _.isDate returns true because date1 is a date object, while the second call returns false because date2 is not a date object.

So, the _.isDate function can be used for date validation by checking whether a given value is a date object or not.
