Method: Array#delete_at

Defined in:
array.c

#delete_at(index) ⇒ nil

Removes the element of self at the given index, which must be an integer-convertible object.

When index is non-negative, deletes the element at offset index:

a = [:foo, 'bar', 2]
a.delete_at(1) # => "bar"
a # => [:foo, 2]

When index is negative, counts backward from the end of the array:

a = [:foo, 'bar', 2]
a.delete_at(-2) # => "bar"
a # => [:foo, 2]

When index is out of range, returns nil.

a = [:foo, 'bar', 2]
a.delete_at(3)  # => nil
a.delete_at(-4) # => nil
