Defclass

Since squint v0.1.15 is it possible to define JavaScript classes, using the defclass syntax. Here is an example that should show most of what is possible. The syntax is inspired by shadow-cljs.

(ns my-class
  (:require [squint.core :refer [defclass]]))

(defclass class-1
  (field -x)
  (field -y :dude) ;; default
  (^:static field a)
  (^:static field b :dude) ;; default
  (constructor [this x] (set! -x x))

  Object
  (get-name-separator [_] (str "-" -x))
  (^:static static-method [_] (str "static field: " a)))

(defclass Class2
  (extends class-1)
  (field -y 1)
  (constructor [_ x y]
               (super (+ x y)))

  Object
  (dude [_]
        (str -y (super.get-name-separator)))
  (^:async fetch [_]
    (js/fetch "https://clojure.org"))

  (toString [this] (str "<<<<" (.dude this) ">>>>") ))

(def c (new Class2 1 2))
