JavaScript to ClojureScript translator

This tool tries to translate as much JavaScript code into ClojureScript as it can. Keep in mind that it might fail or the result will be non-idiomatic Clojure code due to substantial differences between languages.

e.g. Clojure explicitly distincts global and local vars, but JavaScript does not

(def x 1) ;; global
(let [x 2] ;; local
  (/ x 2))

Clojure's data structures are immutable by defalt

(let [x {}]
  [(assoc x :y 1) x])
  ;; [{:y 1} {}]

Use for educational purpose.

javascript-to-clojurescript's Issues

Potential XSS on shared link

Hello,
Probably a design choice, but Javascript input seems to be evaluated
on the client side.

Example:
https://roman01la.github.io/javascript-to-clojurescript/#share-link=120,156,75,204,73,45,42,209,80,202,75,44,46,169,84,168,40,46,86,210,180,230,2,0,76,100,6,160

JSON objects not recognized

I am not an advanced developer otherwise I would attempt a fix myself...

Through trial and error using your amazing translator, I whittled down one of the possible reasons why the large block of js code I tried was not working, it seems to not recognise the JSON formatting, as follows;

const assetData = { "type": "MyType", "item": mydata };

It would be great if you could add a translation rule to deal with JSON

Keep up the good work

Thanks

No translation for with "of"

ref: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of

const array1 = ['a', 'b', 'c'];
for (const element of array1) {
  console.log(element);
}

a[0]=1;

var a=[];
a[0]=1;

(def a #js [])

(set! (aget a 0) 1)

No translation for objects with string keys

Doesn't work for objects that use strings as keys:

var a = {
  "id": "US",
  "name": "United States",
  "value": 100,
  "fill": am4core.color("#F05C5C")
};

Wrong translation direct Object prototype

I am trying to translate Blotter JS sample from the site to Clojurescript

var text = new Blotter.Text("observation", {
  family : "'EB Garamond', serif",
  size : 27,
  fill : "#171717",
  paddingLeft : 40,
  paddingRight : 40
});

from the Translator I get the result (I add js/ by myself)

(def text
  (new (.Text js/Blotter)
    "observation"
    #js {:family "'EB Garamond', serif", :size 27, :fill "#171717", :paddingLeft 40, :paddingRight 40}))

which should be

(def text
  (new js/Blotter.Text 
    "observation"
    #js {:family "'EB Garamond', serif", :size 27, :fill "#171717", :paddingLeft 40, :paddingRight 40}))

the translated one is wrong because the Blotter is called the constructor new Blotter() (I think, correct me if I'm wrong).

ForOfStatement is not implemented

Just want to say that this tool has saved me time and time again. Really appreciate it existing.
Hope you have the time and interest to keep evolving it.

Here's something that popped up as a limitation for me. Error: ForOfStatement is not implemented
A sample of code that triggered it

  var deviceId;
  for (deviceInfo of deviceInfos) {
    if (deviceInfo.kind === 'videoinput' && deviceInfo.label === 'Reincubate Camo') {
      deviceId = deviceInfo.deviceId
      break;
    }
  }
