Lodash _.isDate

Overview

The lodash _.isDate method is a utility function in the Lodash library that is used to determine whether a given value is a JavaScript Date object or not. It returns a boolean value - true if the value is a Date object, false otherwise.

Here is the syntax for using the _.isDate method:

_.isDate(value)

Where 'value' is the value that needs to be checked.

The _.isDate method works by using the 'toString' method of JavaScript's Date object, which returns a string representation of the date. If the value is a Date object, the 'toString' method will return a string that starts with the word "Date". The _.isDate method uses this fact to determine whether the value is a Date object or not.

Some examples where _.isDate method can be put to use are:

Example 1:

_.isDate(new Date); // => true

Explanation: In this example, the isDate method is used to check if a new Date object is indeed a Date object, which returns true.

Example 2:

_.isDate('December 17, 1995 03:24:00'); // => false

Explanation: In this example, the isDate method is used to check if a string is a Date object , which returns false.

One thing to keep in mind is that the _.isDate method works only for JavaScript's built-in Date objects, and not for date-like objects or string representations of dates.

In conclusion, the _.isDate method is a useful utility function that can be used to quickly determine whether a given value is a JavaScript Date object or not.
