Golang



01-Basics


- Go is a compiled language and has different executables for different Operating Systems.

- It is an object oriented programming language but doesn't contain Classes and Objects , rather has Structs instead classes. The concept of overriding and overloading are also not present.

    ```go

    package main

    import "fmt"

    func main() {

	    fmt.Println("Hello , I am Learning GOLANG !!! ")

    }

    ```

- package main() is the entry point of the program

- Statically defined types : once a variable type is declared , it is fixed and hence type cannot be changed. Almost Everything in the Golang is a type.

    	Types Include:

    	1) String                6) Arrays

    	2) Boolean               7) Slices

    	3) Integer               8) Maps

    	4) Floating              9) Structs

    	5) Complex              10) Pointers

    	-- Functions, Channels are types as well

- LEXER ensures the rules of Grammar are properly followed. Also takes care of semi-colons ;)

10-Slices


- Slices are similar to vectors in C++. They are much more powerful than arrays in Go.

- Append vs Make

Make : Allocates fixed memory

Append : Reallocates new memory, therefore making room for new elements

13-Structs


- Similar to classes in OOP languages

- There is no inheritance in Go, no Super or parent concepts
