Because I'm old and new tricks are less interesting, I find $.ajax() much more simple than promise, await, async of native JS.
I have used straight native JS on a couple of smaller personal projects just to get some familiarity with it. However, it's just muscle memory type of getting stuff done with $.ajax() for me.
Also, maybe 20 people use any of the code I write for manipulating DOM. I'm not a UI person. I'm a back end person that has to write front end stuff because nobody else does it.
