How to make a date picker component?

Question

JavaScript

How to develop a data range component that consists of two date picker components that set a time span? That is, there are two inputs, when you click on it, a calendar appears to select a date, as I understand it, you must first create a calendar in pure js, I was looking for how to create a calendar in js, I found only calendars in jquery, etc. Tell me how to solve this problem, where is it described or how?

Answer 2

It is better to take ready-made, because the task does not justify the time spent ... unless the goal itself stands as "you need to make your own date picker component."
