JavaScript compiler: incorrect bignum comparison

[sorawee]

Consider:

method Main() {
  print 24 as bv16 <= 1507 as bv16, "\n";
  assert 24 as bv16 <= 1507 as bv16;
}

This should print "true", which is what Go, Java, C#, and Python output. However, JavaScript prints "false".

Turns out this is about the comparison operator for bigintegers, not bitwise and. It should use .isLessThanOrEqualTo rather than <=.
