$('#id').size !== 0 would not work. I'll bet that your actual code has
.size() instead of .size without the parentheses, right? The size property
is a method, so the !== 0 test would always return true (since a function
reference is never equal to 0).
.length is slightly more efficient than .size() - look at the source code
for the .size method:
size: function() {
return this.length;
}
The only reason the size method exists at all is for compatibility with very
old jQuery code that may have used it back in the days when there was no
.length property.

Personally I do it with `$('#id').size !== 0` but length is goood to i think
