Why split the <script> tag when writing it with document.write()?
I don't really do Javascript programming and was hard to google this but have seen something like this in a couple of different places (by good developers):
document.writeln('<scr'+'ipt src="'+pcheck+'" type="text/javascript"></scr'+'ipt>');
With the split always between the r and the i. What does this achieve?
