buffer is not working?

The same data is returned whether i specify a buffer in const results = qt.get(xywh, buffer); or not.

hi , i got same problem you have got . I just did some debugging . It seems like buffer is set to 0 in line 366 when not using callback. It fixed after assigning correct value to that "buf"

qtree.js#L366

indeed, the first if is not executed, so the buffer should not be overidden if not undefined:

if( (typeof buf == 'function' || typeof buf == 'object') && typeof callbackOrArray == 'undefined' ) {
  callbackOrArray = buf;
  buf = undefined;
}
if( typeof callbackOrArray == 'undefined' ) {
  callbackOrArray = [];
}
if( typeof buf !== 'number' ) {
  buf = 0;
}
