In Go language slice is more powerful, flexible, convenient than an array, and is a lightweight data structure. The slice is a variable-length sequence which stores elements of a similar type, you are not allowed to store different type of elements in the same slice.
In the Go slice of bytes, you are allowed to split the slice after the specified separator using a SplitAfter() function. This function splits a slice of bytes into all subslices after each instance of the given separator and returns a slice which contains these subslices. It is defined under the bytes package so, you have to import bytes package in your program for accessing SplitAfter function.
func SplitAfter(o_slice, sep byte) byte
Here, o_slice is the slice of bytes and sep is the separator. If the sep is empty, then it will split after each UTF-8 sequence. Let us discuss this concept with the help of the given examples:
