How to print/display an array in jquery

I have an array

var arr = [1,2,3,4,5,6,7,8,9,10];

How to display all items of the array using an alert box?

I have tried : alert(arr); and it shows nothing.

Edit: I want display this array like php print_r function.

 output needed like: array["key" => "value", "key" => "value", ...];

    var arr = [1,2,3,4,5,6,7,8,9,10];
    var arrstr="arr[";
    for(var i=0;i<arr.length;i++){
        arrstr+="\""+i+"\" : \""+arr[i]+"\"";   //you can change ":" for "=>", if you like
        if(i!=arr.length-1){//if not the last one ,add "," 
            arrstr+=",";    
        }else{
            arrstr+="]";
        }
    }

    alert(arrstr);

var a = {
  "1": 15,
  "2": 16,
  "3": 17,
}

console.log(a);

As I'm wondering why console.log() hasn't been provided as an answer, here it is.

Do:

console.log(arr);

And open the developper toolbar (F12 on most browsers) and go to the console tab. You should be able to see and expand your array.

var arr = [1,2,3,4,5,6,7,8,9,10];
alert(arr);
for(var i = 0 ; i < arr.length; i++){
alert("key "+ i + " and " + "Value is "+arr[i]);
}

You could also use the JavaScript function toString(). 

alert(arr.toString());

To show them in csv, you can use .join(",") along with array object:

alert(arr.join(", "));

for printing individually: 

$.each(arr, function( index, value ) {
  alert( value );
})
