hmmm

u/tomxor

Haha, regex cannot parse an AST... also: }{a = 1
u/tomxor

I take that back, not sure what's going on, can't see much happening in between textarea and eval in iframe.
u/tomxor

Ahh, i get it: function u(t) {} {a=1} the end part is valid if it's an object literal or ES6 destructuring.
u/tomxor

You could actually use this for intialisation variables instead of checking !t... might be smaller
u/tomxor

i.e }{a=1 rather than !t||(a=1) (saves 4 chars)
