}
function mystr(str) {
pre = "<pre>";
alert(indent);
for (var i=0; i<indent;i++) {
pre+=" ";
}
return pre + str + "<pre>";
}
function printtable(size) {
println("This is a pyramid");
for (var i=0; i<size; i++) {
set_indent(size*2-i);
s="";
for (var j=0; j<i*2+1;j++) {
s += "*";

for(var x = 0; x <= i; x++)// a loop, counting from 0 to whatever value i is currently on
{
document.write("*");//writ

But the function of the code is different:
..........................
<html>
<head>
<script type="text/javascript">
var indent;
function println(str) {
document.write(str);
}
function set_indent(i) {
indent = i;
}
function mystr(str) {
pre = "<pre>";
alert(indent);
for (var i=0; i<indent;i++) {
pre+=" ";
}
return pre + str + "<pre>";
}
var indent = 0;
function printtable(size)
{
println("This is a pyramid");
for (var i=0; i<size; i++)
{
indent = size*2 - i;
s = "";
for ( var j=0; j<indent; j++ )
{
s += " ";
}
for (var j=0; j<i*2+1;j++)
{
s += "*";
}
document.write( "<pre>" + s + "</pre>" );
}
}
</script>
</head>

printtable(5);

return pre + str + "<pre>";

var indent = 0;
function printtable(size)
