buffer loop is NaN

[cymplecy]

is converted to

var chars, i;

chars = (Buffer.from('ABCDE', "utf8"));
var i_end = (chars.length);
var i_inc = 1;
if (1 > i_end) {
  i_inc = -i_inc;
}
for (i = 1; i_inc >= 0 ? i <= i_end : i >= i_end; i += i_inc) {
  chars[NaN] = 32;
}

Hi Simon (@cymplecy ),
can you please post your flow here. Then I will have a look at it this evening.

I don't think Blockly flows copy and paste OK so here is pastebin link

Fixed it in get and set - pull request made

var chars, i;

chars = (Buffer.from('ABCDE', "utf8"));
var i_end = (chars.length);
var i_inc = 1;
if (1 > i_end) {
  i_inc = -i_inc;
}
for (i = 1; i_inc >= 0 ? i <= i_end : i >= i_end; i += i_inc) {
  chars[(i - 1)] = 32;
}
