actionscript 3 - AS3 Add array to another array -

example of problem.

 var array_1:array = new array();  array_1[0] = [2,4,6,8];   var array_2:array = new array();  array_2[0] = [10,12,14,16];  array_2[1] = [18,20,22,24];   // , out come want    trace(array_1[0]) // 2,4,6,8,10,12,14,16,20,22,24   // did try  array_1[0] += array_2[0] didn't work    

any suggestion great.

this perform looking , allows add multiple rows of data array_1 or array_2

var array_1:array = new array(); array_1[0] = [2,4,6,8];  var array_2:array = new array(); array_2[0] = [10,12,14,16]; array_2[1] = [18,20,22,24];  var combinedarray:array = new array(); for( var i:int = 0; < array_1.length; i++ ) {     combinedarray = combinedarray.concat(array_1[i]); } for( = 0; < array_2.length; i++ ) {     combinedarray = combinedarray.concat(array_2[i]); }  trace(combinedarray);
