JavaScript » Array » slice
- Syntax:
- Array.slice(begin[,end])
The slice method creates a new array from a selected section of an array.
The original array is unaffected by this but, if a string or number in one array is altered,
it is not reflected in the other, whereas a change to a referenced object can be
seen in both Array objects. The slice method uses the zero-based array index to determine
the section out of which to create the new array. It extracts up to, but not including,
the 'end' element (if no 'end' is specified, the default is the very last element).
If you use a negative index for the 'end', this specifies an element so many places
from the end.
Examples
Code:
trees = ["oak", "ash", "beech", "maple", "sycamore"]
document.write(trees.slice(1,4))Output:
ash,beech,mapleExplanation:
This code creates an array called 'trees' and then displays a 'slice' of it.
Code:
trees = ["oak", "ash", "beech", "maple", "sycamore"]
document.write(trees.slice(1,-2))Output:
ash,beechExplanation:
This code would display the second through the third to last elements of the array:
