// JavaScript to illustrate reverse() method
function pyVisualizer() {
//Original Array

//Reversed array
var new_arr = arr.reverse();
document.write("<br>");
document.write("output using reverse() method </br>");

// expected output: 4,5,2,1
}
runExample();
</script>
Output:
Output
4,5,2,1

//Reversed array
var new_arr = arr.reverse();
document.write("<br>");
document.write("output using reverse() method </br>");
document.write(new_arr);
// expected output: RDBMS,C++,C,Java
}
