Go Append method

Append is used to add elements to the end of a slice and return results.
Look at the code:

" FMT " Func Main () {x:= []int {1,2,3}y:= []int {4 ,5,6}// Note the following two differences between FMT. Println (Append (x,4,5,6)) fmt. Println (Append (x, y ...));}

Output Result:

[1 2 3 4 5 6]
[1 2 3 4 5 6]

There are two ways to use append:
Slice = append (slice, elem1, elem2)
Slice = append (slice, anotherslice ...)

In the first usage, the first argument is slice, and you can add multiple parameters later.
If you are stitching together two slice, you will need to use the second one, add three points after the name of the second slice, and this time append only supports two parameters and does not support any number of arguments.
