In go language, the buffer belongs to the byte package of the Go language, and we can use these package to manipulate the byte of the string. For example, suppose we have a string. We can read the length of the string with the len function, which will return the numeric length, but what if the strings are too large.
To create a byte in Go, assign an ASCII character to a variable. A byte in Golang is an unsigned 8-bit integer. The byte type represents ASCII characters, while the rune data type represents a broader set of Unicode characters encoded in UTF-8 format.
In the situation where I need to add an unknown amount of data to a slice of byte, let say in a loop, I could either way use the builtin function append() or create a new Buffer and use the Write() function.
