A `string` is an immutable container of `uint8` bytes. They are meant to represent text encoded in UTF-8, but not every byte is guaranteed to be valid Unicode. There are only a few instances where strings are implicitly encoded: * in `for i, r := range s`, the `r` is a Unicode rune * in `rs := []rune(s)`, `rs` is a string of Unicode runes In these cases, all invalid Unicode bytes are converted to `U+FFFD` (the replacement character). |

String
A string is an immutable container of uint8 bytes.
They are meant to represent text encoded in UTF-8, but not every byte is guaranteed to be valid Unicode. There are only a few instances where strings are implicitly encoded:
in for i, r := range s, the r is a Unicode rune
in rs := []rune(s), rs is a string of Unicode runes
In these cases, all invalid Unicode bytes are converted to U+FFFD (the replacement character).
Bool
Numeric Types
signed integers: int8, int16, int32, int64, and int
unsigned integers: uint8, uint16, uint32, uint64, and uint
uintptr
floating point numbers: float32 and float64
complex numbers: complex64 and complex128
byte is an alias to uint8, and rune is an alias to int32.
