Return Value: It returns the items in the enum which does not satisfies the condition in the block. It returns an enumerator if no block is given.
Example #1:
# Ruby program for reject method in Enumerable # Initialize enu = (1..10) # Prints enu.reject { |obj| obj % 2 == 1} |
Output:
[2, 4, 6, 8, 10]
Example #2:
# Ruby program for reject method in Enumerable # Initialize enu = [1, 7, 10, 11] # Prints enu.reject |
Output:
Enumerator: [1, 7, 10, 11]:reject
