So, another 'X' JS framework just came out, gained some traction and now you see it in every other tweet, post, or youtube video.

Most of the devs have learned the hard way, that trying to master each and every tech can ultimately leave you as a master of none.

On the other hand, the hype won't usually be there if there wasn't something attractive on the tech it comes from, meaning it would potentially be worth checking out.

How do you normally approach it? Do you always make sure you are among the first ones to check it out and do 'cool' projects or do you not pay much attention to it, focusing on mastering your current stack instead?
