JavaScript implements array transpose

Array transpose
var arr=[[2,5,6,8],[8,5,6,9],[9,6,2,1]];
var arrnew=[];//defines a new array
for (Var i=0;i<arr[0].length;i++) {
arrnew[i]=[];//open space for new arrays
}
JS arrays can add data dynamically
Traversing an old array
for (Var i=0;i<arr.length;i++) {
Iterate through each of the specific values
for (Var j=0;j<arr[i].length;j++) {
ARRNEW[J][I]=ARR[I][J];
}
}
Successfully transpose, traversing the arrnew array is just a transpose array
To traverse the output of our new array
for (Var i=0;i<arrnew.length;i++) {
for (Var j=0;j<arrnew[i].length;j++) {
Document.writeln (arrnew[i][j]+ "&nbsp;");
}
Document.writeln ("<br/>");
}
