Suppose I have an array
var myArray = [1,2,3,4,5];
and I want the first 3 elements, I can do the following
myArray.slice(0,3);
which return an array with the first 3 elements
[ 1, 2, 3 ]
This does not modify the original array in any way, it just returns a new array
The function slice has the following signature,
slice ( beginIndex, endIndex ) where the index is zero based i.e. the first element in a an array starts at index 0.
You could also access the array from the end using negatives indices for example,
myArray.slice(-3, -1);
returns
[ 3, 4 ]
Next we will look at splice......until next time!
