Truncating an Array in JavaScript
How do you truncate an array in JavaScript?#
There are two ways of truncating an array in JavaScript. One takes advantage of the fact that the length
property of the Array
object is writable, another uses the splice
method of the Array
object.
Truncating JavaScript array using the length property:
In the above code the array is truncated to two items, and only 'apple' and 'mango' are left.
Truncating JavaScript array using the splice()
method:
In the above code too the array is truncated to two items. Splice will also return the items that were truncated from the array.
Choose which ever way fits your need. If you just need to truncate the array, you could go with the length
method, if you need to get the items that were truncated you should use the splice()
method.
Happy array truncating!
