Javascript Slice - Use Slice to Get Items from an Array in Javascript

Javascript Slice will create a new array based on the index numbers you specify in the parenthesis.

i=new Array("Hi", "Hello", "Cheers", "Greetings");

i=i.slice(0,2);

document.write(i);

Which Prints:
Hi,Hello

-We create an array and name it i because we like one letter names.
-We use Javascript's built-in slice method on our array and store it there as well.
-We use Javascript's built-in document.write command to print to the browser.

NOTE: Array Index Numbers start at 0 for the first position. In our example, we started at the 0 position and went through to the 2 position. Notice that the 2 position is NOT stored into the array. Think of the second number as a stopping point.

NOTE: The ending index number is optional. By default, slice will go all the way to the end of the array unless you specify an ending.

Example:
i=new Array("Hi", "Hello", "Cheers", "Greetings");
i=i.slice(2);
document.write(i);

Prints:
Cheers,Greetings

Since we didn't specify an ending point, slice started at index number 2 (Cheers) and stored everything until there was nothing left to store.
