Moar squint optimizations. If objects aren't shared, we are free to mutate them, even when assoc instead of assoc! is used.

Squint CLJS now emits more performant code for assoc, assoc! and get when objects can be inferred or are type hinted using ^object

I wanted to speed up = (equals) in ClojureScript: when you know one of the (2) operands is a primitive, you can drop down to `===` instead of going through the `cljs.core/=` functions

But can't do this because idiots can override the behavior of = via protocols on primitives :-s

Small tweak to #squintcljs. When using ^object type hints, assoc and assoc! compile down direct object manipulation without calling into the stdlib

I'm probably not the first to think about this one? Split a string into two at cursor in emacs. Works nicely with str in #clojure

(defun split-string-at-point ()
(interactive)
(when (nth 3 (syntax-ppss)) ; are we inside a string?
(insert "\"\"")
(backward-char 1)))

I should tone down the excitement a little bit. It's much much faster when you use constants in str, but still only 4x faster when you use all variables.

Announcing a little but fun macro as library that optimizes CLJS str almost 300x.

Found a pretty nice optimization for str in #squintcljs

(str "Hello: " (+ 1 2 3) nil "Dude")

=>

`Hello: ${1 + 2 + 3 ?? ""}Dude`

So str -> template string + null/undefined check.
This performs much better than Array.join('').

But... is it worth it?

Included a small compile time optimization for = : when you compare with a number, or keyword/string (same thing in squint), which is a pretty common pattern, then = will still compile into === :
