Hey! I am Currently learning Go Lang, and I am taking some basic Notes on my Notion and though I'd also just publish them here. They are not well thought out or well written but it's just me taking notes from time to time for my reference.

I am taking the Udemy Course by Maximilian Schwarzmüller,

Notes

import "fmt"

func main(){
    fmt.Print("Hello World")
}

go run app.go

• Main function is the entry point for whole GO application
• Print is a method that comes from the fmt package
• Strings are only allowed in double quotes or backticks only

• Every Go file needs a package imported that will be same as the file name

• Idea for packages is to organize code

• package can be made up of multiple files

Explicit type declaration

• Go can by itself get the type of values being stored in the variable, but we can also declare a type so that we can say what value can be stored there and with that we can remove any extra type conversion

    var investmentAmount float64 = 1000

• explicit type can be added after the variable name
