push(item : T)

Append. Pushes one value to the end of self, given that the type of the value is T (which might be a single type or a union of types). This method returns self, so several calls can be chained. See pop for the opposite effect.

a = ["a", "b"]
a.push("c") # => ["a", "b", "c"]
a.push(1)   # Errors, because the array only accepts String.

a = ["a", "b"] of (Int32 | String)
a.push("c") # => ["a", "b", "c"]
a.push(1)   # => ["a", "b", "c", 1]

push(*items : T)

Append multiple values. The same as push, but takes an arbitrary number of values to push into self. Returns self.

a = ["a"]
a.push("b", "c") # => ["a", "b", "c"]
