<body>
<script language="javascript" type="text/javascript">
function fac(n){
if(n==0) return 1;
var val=1;
for(;n>0;n--) val*=n;
return val;
}
function combi(n,k){
return fac(n)/(fac(n-k)*fac(k))
}
var i,j;
for(i=0;i<10;i++){
for(j=0;j<10-i;j++) document.write(" ");
for(j=0;j<=i;j++) documnet.write(combi(i,j)+" ");
document.write("<br>");
}

급한대로 파스칼의 삼각형 만들어서 if, for, 함수정의 공부한거 티내려고 했는데 안되네요 ㅠ
