What is the purpose of the append function in Go?
- To merge two slices.
- To remove elements from a slice.
- To resize an array.
- To add elements to a slice.
The append function in Go is used to add elements to a slice. It takes an existing slice and one or more values to append and returns a new slice with the added elements. Importantly, if the underlying array of the slice is too small to accommodate the new elements, append will allocate a larger array and copy the existing elements, ensuring efficient memory management. Misusing append can lead to unexpected behavior and memory issues.
