can someone explane me arr??? pls

Answer 1

@Bagshot: the question is tagged with 'javascript' not 'java' ^^

@Ivica:

You're probably refering to a code example using a variable named 'arr' to store an array (list of values)...
In JS, you can declare array by two main ways:

var arr = new Array(); // explicit creation of Array object

... or:

var arr = [ ]; // literal notation, implicit Array object created

Answer 2

Do you mean "arrr, I hit my toe!"? Or arr as in array?

An array is just a collection of strings, intergers, floats, etc. You can access each element of the array using its index number.

int[] arr = { 5, 4, 3, 2, 1};
string[] arr = {"sololearn", "is", "cool"};

It doesn't have to be called arr, by the way.

Ok, my mistake. It's actually c#, but yeah should have read it better.
