NOTE: If your project was created with an operator-sdk version prior to v1.0.0 please migrate, or consult the legacy docs. As an alternative to C's three-statement for loop, Go's range expressions allow concise iteration over arrays, slices, strings, maps, and channels. Go Operator Tutorial An in-depth walkthough of building and running a Go-based operator. Go adds literal syntaxes for initializing struct parameters by name and for initializing maps and slices. Methods may return multiple values, and returning a result, err pair is the conventional way a method indicates an error to its caller in Go. Semicolons still terminate statements but are implicit when the end of a line occurs. This contrasts with C's int i = 3 and const char *s = 'Hello, world!'. A combined declaration/initialization operator was introduced that allows the programmer to write i := 3 or s := 'Hello, world!', without specifying the types of variables used.

Go's syntax includes changes from C aimed at keeping code concise and readable. With GCC the combination is gccgo with LLVM the combination is gollvm. gofrontend, a frontend to other compilers, with the libgo library.Google's self-hosting 'gc' compiler toolchain targeting multiple operating systems, and WebAssembly.The language is often referred to as Golang because of its former domain name,, but the proper name is Go. Go is syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency. Go TutorialGo is a statically typed, compiled programming language designed at Google by Robert Griesemer, Rob Pike, and Ken Thompson. Go Add - Append - Change - Access - Copy Slices.

Go Print Output text in color in console.

Go Output Functions - Print - Println - Printf.

we'll talk more on some other specifics in the next tutorial, such as how or why this main function even runs. we can reference other packages from fmt with. Println is a function from the fmt library define, name, parms, and your code goes in curly braces. In this case we import fmt, which brings in In Go, the way you can do single-line comments is with // and you can do multi-line comments with /* and end with */ package main //go programs consist of packages, and start with main If you do not know what comments are in programming, they are ways to write notes and such in your code that will not be run as actual code when your program runs.

I will do this by commenting above or beside the lines what they do. If you made it this far, congratulations on your first Go program! Let's cover briefly what each line is doing. To run this, we can do go run gointro.go, and you should see: Welcome to Go! Let's write a quick basic Go program to see if we've got everything setup and ready to go: To run your files, you use your terminal / cmd.exe and use the syntax: go run YOURFILE.go

Not only does Go have web frameworks, the language itself comes out of the gate with full web support, a built in web server, and could be considered already a low-level web framework. For me personally, my main interest in Go is for web development, but I can see it being useful for a variety of high-volume types of tasks and just systems in general. Go is a static-typed language (as opposed to dynamic typing with something like Python), and has concepts like concurrency baked in right from the start. The problem is, however, C++ isn't the most enjoyable language to program in, nor is it the most friendly to learn. If you scale out Python to millions of instances, you pay quite the price in performance and cost as opposed to if you had written the same program in C++. A language like Python is great for rapid development and many tasks, but, due to the GIL and dynamic typing, it can sometimes be slow. Go was developed by Google to solve challenges that they were facing, purpose built from the ground up. Because of this, we're going to learn and immediately apply at the same time as we move through these concepts.ДЇirst off, why might we be interested in the Go programming language? For me, since I mainly program in Python, I am going to compare it to a high-level language like that. Go is a programming language where you could easily run through the basics, and then be totally lost when it comes to actually applying it to some actual task. In this series, we're going to cover setting up and the basics of using Go in a practical way. Hello and welcome to a Go Language programming tutorial.
