yeet and yoink?

[gdanov]

while fooling around with latest updates I saw these new operations. Can't find them explained anywhere and keys look similar to slurp and barf?

[mickeynp]

They're like them, yes. But slurp/barf has limited utility in most languages due to the wildly different syntactic elements you're likely to work on. So it'll work (somewhat) with JSX and other minor things like that. It's definitely an underdeveloped feature, for sure.

tried it several times, get "no valid sibling node"
One example I used :

const x = 1+(2+3)+4

anywhere inside the parens

It only works in very few, limited circumstances.
