I would use vanilla JS rather than jQuery now that most browser compatibility issues are sorted. But most of my work doesn't need to support versions of IE older than 11.
which is exactly what they are doing (also , nominally vanilla JS is even more legacy than JQ)
isn't jQuery nowadays also using all native functions of a browser?
I still find the regex selector so powerful in jQuery.
What do you gain? What do you lose?
jQuery has a better syntax and smaller coding footprint.
