What is hello world?

Welcome to WordPress. This is your first post. Edit or delete it, then start writing!

This website is powered by WordPress. WordPress is the most common content management system (CMS) on the world wide web.

When you install WordPress for the first time, the program will publish a default post, call “Hello World”.

But What is hello world?

The first code any programmer learns also says a lot about the craft.

First introduced in the BCPL programming language, “Hello World” is a software program or script that introduces someone to a programming language or for testing a language or its compiler.

The code prints the message “Hello World” to the computer screen to confirm that the program is working on the basic level.

Below is an example of how to print “Hello World!” in Python.

hello world

Did you get it? 

“Hello, World!” definitely has a purpose and a place – but after the very first “Hello, World!” lesson, you’re done – there’s no need to mention those words again. In Java back at Uni, we then started learning about collecting user input and doing basic maths operations on it. In Laravel, we started building a collection of Books. In Vue.js, we build a To-do app. After we’ve confirmed our code is running – c’mon System.out.println, echo, alert, console.log, whatever – it’s on to learning skills with real-world application.

What would you prefer to learn? How a model “HelloWorld” can be related to a number of “HelloWorld’s”, or how a Book can be related to a number of Genres? What makes more sense in your mind? [1]

Here also I collect some Hello world examples for you 🙂
