Initialize an array with random indices in Javascript

Question

I try to fill an array randomly. I have an rows array:

rows = ['1','0','2','1','3'];

and columns array:

columns = ['0','0','1','2','3'];

and a button array:

butArray = [];

I initialized button array. What I try to

printArr[rows[i]][columns[i]] = butArray[i];

How exactly should I use loop here?

@Rajesh I try to locate buttons dynamically, I take the rows , columns, button values from user and according to this I print the buttons on the screen. — Emin Çiftçi

@EminÇiftçi Your question is not clear. Please show us what is inside butArray[] and what is the final result — Weedoze

  console.log("cds")
  rows = ['1','0','2','1','3'];
  columns = ['0','0','1','2','3'];
  butArray = ['qwe','qwe','qewe','qew','qwe'];//some values
  var printArr = [];
  for(var i=0 ; i<columns.length ; i++){
    if(printArr[rows[i]] == undefined)
    printArr[rows[i]] = []
    printArr[rows[i]][columns[i]] = butArray[i];

  }
  console.log(printArr);
}
