golang. Go is a programming language built to resemble a simplified version of the C programming language. It compiles at the machine level. Go was created at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. In some languages this would trigger a null pointer exception, but in Go it is common to write methods that gracefully handle being called with a nil receiver (as with the method M in this example.)

Using fmt.Println to output data structures is really just for easy debugging, the formatting is pretty arbitrary you could get more reliably formatted output in correct Go if you used fmt.Printf ("%#v\n", i).

Contribute to golang/go development by creating an account on GitHub. Similarly, in Golang we have slice which is more flexible, powerful, lightweight and convenient than array. As slice is more flexible than array therefore, its flexibility is determined in terms of its size. Just like an array, it has indexing value and length but its size is not fixed. When we declare a slice we do not specify the size of it. ….
