Hi, I think I found a KotlinJS compiler bug. I know I should report this via YouTrack (and I will) but I just wanted to double check here:

class ProducesUninitializedTmpVarInJs(private val bar: (idx: Int) -&gt; Boolean) {
    private var idx = 0
    fun foo(): Boolean = true &amp;&amp; bar(idx++)
}

/*
  ProducesUninitializedTmpVarInJs.prototype.foo = function () {
    var tmp$, tmp$_0, tmp$_1, tmp$_2;
    tmp$_2 = tmp$_1(tmp$_0); // tmp$1 is 'undefined' at this place!!!
    if (true) {
      tmp$_1 = this.bar_0;
      tmp$_0 = (tmp$ = this.idx_0, this.idx_0 = tmp$ + 1 | 0, tmp$);
    }
     else
      tmp$_2 = false;
    return tmp$_2;
  };
 */

As you can see tmp$1 is ‘undefined’!

alexander.egger: yes it is, please report it
