Low GC (Garbage Collection) pause (100 microseconds).To receive and provide small amounts of data occassionally.

Due to its small size, Go can be a good fit for use on a Raspberry Pi small computer.

Golang can be transpiled (like BabelJs) using GopherJs into JavaScript for isomorphic web applications, where business logic, templates, template functions, and validation logic, can be shared across client and server environments, for code re-use. So Go avoids the “callback hell” associated with JavaScript’s single-thread operation.

Go’s built-in concurrency goroutines for threads communicating through channels were not patched in over time.

Golang does not have a “where” clause, just if.

Variables are declared with external scope by being named starting with a capital letter.

Networking is baked into its standard library and runtime.

No parentheses surround the three components of the for statement.

Needs to be built by a compiler (not interpreted like Python).

Go is 25% faster than Python at API calls.

Go can be used with libraries to create GUI as well as CLI Terminal programs.

VIDEO: Used by developers of C and Unix (including Brian Kernigan, the K in awk, who literally wrote the book on C, and co-creator of Go with Alan Donovan).

Go is strongly typed (must specify data type in commands).

* This means Go installers don’t have dependencies like Java and Python programs. The Go compiler is programmed in Go itself rather than C.

fmt, a contraction of “format” (pronounced “frumpt”) is Go’s single way to format output.

Compiler doesn’t issue warnings, just errors.

This can be done by setting the GOROOT environment variable to point to the directory in which it was installed, although this is not recommended as it comes preset with the tooling.This is a quick step-by-step introduction to the Go programming language (GoLang).

GOLAND GOPATH INSTALL

It is possible to install the Go tools to a different location. To check the current GOROOT enter the following command: C:\Users\%USERPROFILE%\go env GOPATH It should always be set to the installation directory. GOROOT is for compiler and tools that come from go installation and is used to find the standard libraries. However, it is still used to store downloaded source code in pkg and compiled commands bin. When using modules in Go, the GOPATH is no longer used to determine imports. Every command is named for its source directory. Each target operating system and architecture pair has its own subdirectory of pkg.

pkg: It holds installed package objects.

The path below this directory determines the import path or the executable name.

GOPATH contains 3 directories under it and each directory under it has specific functions: To check the current GOPATH enter the following command: C:\Users\%USERPROFILE%\go env GOPATH To check this, enter the following command: On Windows: If the environment variable is unset, GOPATH defaults to a subdirectory named “go” in the user’s home directory. The go get tool downloads packages to the first directory in GOPATH. It is implemented by and documented in the go/build package and is used to resolve import statements. GOPATH, also called the workspace directory, is the directory where the Go code belongs. The paths of gopath and goroot can be modified explicitly if required. GOPATH and GOROOT are environment variables that define a certain arrangement and organization for the Go source code. Instead of being run directly, programs in that set are usually invoked by the go program. There is a set of programs to build and process Go source code.
