javascript - I want to replace all values with another array values , both arrays are in same size -

eg:

var array1=array(1,2,3,4,5,6);

var array2=array(7,8,9,10,11,12);

after replacing array2 array1 values resulting array should be

var array1=array(7,8,9,10,11,12);

use slice:

array1 = array2.slice(0); 

this take copy of array2, not make reference it, if make changes array2 won't reflected in array1.
