Group an array to form three arrays based on the index

Question

I want to sort an array in a way that it gives back three arrays. So

var myArray = [\'1\',\'2\',\'3\',\'1\',\'2\',\'3\',\'1\',\'2\',\'3\',\'1\',\'2\',\'3\',\'1\'         


        

Answer 1

var myArray = ['1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3','1','2','3'];

var myArray1 = [];
var myArray2 = [];
var myArray3 = [];
for(var i = 0; i < myArray.length;) {
    myArray1.push(myArray [i++]); 
    myArray2.push(myArray [i++]);
    myArray3.push(myArray [i++]);
}
