This function removes all values in the list that satisfies the callback function. The removed values will be returned in a new list. An empty list is returned if no value is removed.
|callback||closure (required)||Closure to execute on each value.|
|limit||int (optional)||Limit the number of items to remove. When negative, removal starts at the end of the list and removes at most the absolute value of limit.|
Explanation of the callback argument:
|list||item, index||Iterate over items in the list. Both item and index are optional.|
limmit is a negative value, removing starts at the end of the list. Note that in this case the returned list still contains the removed items in the same order as they were in the original list.
A list with the removed items from the list. The order of items in the new list will be the same as the original order in the list.
This code shows an example using remove() on a list:
tmp = [1, 2, 3, 4]; [ tmp.remove(|x| x%2==0), tmp, ];
Return value in JSON format
[ [ 2, 4 ], [ 1, 3 ] ]
Example with a negative limit:
tmp = [1, 2, 3, 4, 5, 6, 7, 8]; // Remove the last two items from the list which pass the test [ tmp.remove(|x| x%2==0, -2), tmp, ];
Return value in JSON format (note that the order is equal to the original list)
[ [ 6, 8 ], [ 1, 2, 3, 4, 5, 7 ] ]
