为什么无法输出呢？

<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>二维数组</title>
<script type="text/javascript">
var myarr =new Array();
for(var i=0;i<=2;i++){
var myarr[i]=new Array
for( var j=0;j<=5;j++){
myarr[i][j]=i*j;
document.write(myarr.[i][j]+</br>);

}
}

var myarr2 =[[0,0,0,0,0,0],[0,1,2,3,4,5],[0,2,4,6,10]];

</script>
</head>

<body>

<!DOCTYPE HTML>

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<title>二维数组</title>

<script type="text/javascript">

    var myarr =new Array();

    for(var i=0;i<=2;i++){

        myarr[i]= new Array();

        for( var j=0;j<=5;j++){

            myarr[i][j]=i*j;

            document.write(myarr[i][j]+"</br>");

        }
        
        var myarr2 =[[0,0,0,0,0,0],[0,1,2,3,4,5],[0,2,4,6,10]];

    }

改过后的代码

document.write(myarr.[i][j]+"</br>"); </br>加双引号;

var myarr[i]=new Array 改为 myarr[i]= new Array();
