Is Javascript Phaser (for games) better than the regular JavaScript graphical capabilities?

Hi,
I've been doing work in Javascript this week, and I don't want to end up using inferior packages.

I'm using CSS and HTML to put up a chess board now. Are the javascript primitives for drawing not quite as solid as Phaser?
I've also been watching the Udemy javascript lectures. I'd like to use its apparent effectiveness (made by gamers for gamers?)

I like the preload, create, update .. interface for the various components of the project.
It does sound, in addition.

Any insights or experience concerning this assessment? Do all devices support Phaser?

Thanks
