Description

The Append function creates a new array that is the result of combining the base Array followed by the elems. This is a specialized function, and only works with arrays and not pages.

Parameters

Argument Type Definition and Requirements

base

The base array.

elems

Value or Array

The elements to add to the end of the base array.

Returns

A new array containing both the base array followed by the elems.

Examples

The following example creates a new array containing the base array’s values, (1, 2, 3), followed by the elems array’s values, (4, 5, 6).

client.Query(
    Append(Arr(4, 5, 6), Arr(1, 2, 3))
);
Arr(LongV(1), LongV(2), LongV(3), LongV(4), LongV(5), LongV(6))
result, err := client.Query(
	f.Append(f.Arr{4, 5, 6}, f.Arr{1, 2, 3}))

if err != nil {
	fmt.Fprintln(os.Stderr, err)
} else {
	fmt.Println(result)
}
[1 2 3 4 5 6]
System.out.println(
    client.query(
        Append(
            Arr(Value(4), Value(5), Value(6)),
            Arr(Value(1), Value(2), Value(3))
        )
    ).get());
[1, 2, 3, 4, 5, 6]
client.query(
  q.Append([4, 5, 6], [1, 2, 3])
)
.then((ret) => console.log(ret))
.catch((err) => console.error('Error: %s', err))
[ 1, 2, 3, 4, 5, 6 ]
result = client.query(
    q.append([4, 5, 6], [1, 2, 3])
)
print(result)
[1, 2, 3, 4, 5, 6]
client.query(Append(Arr(4, 5, 6), Arr(1, 2, 3)))
[ 1, 2, 3, 4, 5, 6 ]
