Do I need to use js bam?

Question

BEM

When I searched for information about bam I found a lot of videos and articles about bam css , but when I searched for bam js I did not find articles or videos with detailed explanations .
It seems to me that if there are not enough articles and videos about bam js, then you can just use js instead of js bam.

Answer 1

Not necessary and even harmful. Bundlers themselves break applications into chunks and load them dynamically as needed. The only option is when you write all the code yourself then it is possible

Answer 2

1) If you see that in vacancies there is often a requirement to know this or that technology, then of course study and use it.
2) If you personally like technology, study and use it in your personal projects.
In other cases, it makes no sense.
