A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

	user := h.service.GetByUsername(username)
	if user == nil || user.Password != password {
		return echo.ErrUnauthorized

Go (Golang) Standard Library Interfaces (Selected)

This is not an exhaustive list of all interfaces in Go's standard library. I only list those I think are important. Interfaces defined in frequently used packages (like io, fmt) are included. Interfaces that have significant importance are also included.

All of the following information is based on go version go1.8.3 darwin/amd64.

tl;dr

• JSON is faster for small size data
  • map (key size < 50 and Unmarshalling intensive workload)
  • single struct
• gob is faster for big size data
  • map (key size > 50 or Marshalling intensive workload)
  • slice
