What is Go?
Go is an open-source and statically typed language made by Google. It’s suitable for server-side programming, cloud-based development, command-line tool development, and game development. The language is simple, fast (meaning it compiles to machine code quickly), and easy to learn. It’s also known for its concurrency, which allows it to run multiple instructions simultaneously. It also has a fast garbage collector that ensures that the memory is not clogged with garbage, which improves performance. Companies such as Atlassian, Xiaomi, Algolia, Dell, and Stripe use Go.
Go syntax
A Go file typically comprises several components that contribute to the overall structure and functionality of the code. These components include:
Package declaration: The
packagedeclaration states the package to which the current file belongs. It defines the namespace for the code within the file. For example:
package main
Import packages: The
importstatement is used to include external packages that provide additional functionality required by the code. It allows access to functions, types, and variables defined in those packages. For example:
import ("fmt""time")
