It has been a long time since the last time I wrote a post here, however, now that I have a little more free time I plan to resume writing. I hope this post is short. I want to tell you where the inspiration for the name of this blog came from... Since I was a child I have always been very interested in astronomy, however I never saw it possible to study something related in a third world country. However, that is not the story...

In the project I am currently working on, a specific need arose, we should protect certain routes of a web application from certain user roles (for security reasons). For example, we have a page where administrators can add and delete users, this power can only be held by us (this must be a private page). **React Router v6** (latest version), it does not offer any functionality for this type of situation, the implementation is the developer's task.

In older versions of ECMAScript this was a bit cumbersome: "Destructuring" arrays: ```js var myArr = ["Andres", "Bedoya"] // ES5 and previous var firstName = myArr[0] var lastName = myArr[1] // ES6 const [firstName, lastName] = myArr ``` "Destructuring" objects: ```js var myObject = { firstName: "Andres", lastName: "Bedoya" } // ES5 and previous var firstName = myObject["firsName"] var...
