With the assistance of AI, the journey of learning coding can be quite different from the traditional process. You can learn multiple coding languages at the same time; all you need to know is how to use the correct prompts. Once you have learned the basic concepts, you can instruct AI to take care of the rest for you.

Let’s kick off our future coding learning journey - Hello World.

The "Hello World" project is a simple program that is typically created as the first project when someone is learning a new programming language. The goal of the project is to introduce the basic concepts of the language, such as how to write and run a program, how to use variables, how to print output, and how to use basic syntax.

1. Dart

Dart is an object-oriented, client-optimized programming language that is developed by Google. It is designed to be used for developing web and mobile applications, as well as server-side applications. Dart is a statically typed language, which means that type checking is done at compile-time rather than at runtime.

One of the key features of Dart is its support for building user interfaces through a reactive programming model, using a library called Flutter. Flutter is a popular mobile development framework that is built on top of Dart, and it allows developers to create native mobile applications for iOS and Android with a single codebase.

2. Javascript

JavaScript is a programming language that is commonly used to create interactive effects within web browsers. It is an object-oriented language that is based on a prototype model, which means that objects inherit properties and methods directly from other objects.

JavaScript was originally created by Brendan Eich at Netscape in 1995, and it has since become one of the most popular programming languages in use today. JavaScript can be used to add functionality to web pages, create dynamic user interfaces, and build web applications. It is also used on the server-side with Node.js, a platform that allows developers to build server-side applications using JavaScript.

9. C/C++

C and C++ are programming languages that are widely used for system-level programming, operating systems, game development, and embedded systems.

C was developed in the early 1970s by Dennis Ritchie at Bell Labs and is a procedural, low-level programming language. It is known for its efficiency, portability, and direct access to system hardware.

C++ is an object-oriented programming language that was developed in the 1980s as an extension of C. It includes features such as classes, inheritance, and polymorphism, which make it easier to write complex programs.

C++ is commonly used for developing large-scale applications, such as video games and operating systems.

Many high-level programming language interpreters, including but not limited to Dart, Java, Python, JavaScript, and Go, are written in C and C++.

Both C and C++ are compiled languages, which means that the code is compiled into machine code before execution.

Summary:

Now that we have covered the concept of the Hello World project in different languages, let's make a quick summary of what we have learned in this unit.

1. If we want to learn a new coding language, we just need to know the name and then ask AI how to write a Hello World program for it.

We also provided some AI prompts for other popular coding languages that were not mentioned in this unit:

• Can you write a Hello World program in Ruby?
• Can you write a Hello World program in Rust?
• Can you write a Hello World program in Perl?
• Can you write a Hello World program in Lua?
• Can you write a Hello World program in Bash?

2. Now, we know how to print strings or numbers to the screen or console.

We listed some print functions that we saw in this unit:

print
console.log
echo 
System.out.println
println
printf
std::cout
fmt.Println
NSLog

You don't need to remember all of them, just the word "print" is enough, as we can ask AI for the function name and how to use it at any time.

We also provided some AI prompt samples for how to print strings or numbers in a specific language:

• How can I print a string in JavaScript?
• How can I print a string and number in Dart?
• How can I print a number in Python?
• Can you explain how to use the printf function in C?
• How can I print a number in hexadecimal format in Dart?

3. We have learned about some coding languages and frameworks. Let's list all of them here:

Dart
JavaScript
TypeScript
Python
PHP
Swift
Java
Kotlin
C
C++
Objective-C
Go
React framework
Flutter framework

Again, you don't need to remember all of these names. Just having a general impression is enough, as we will talk and learn about them every day from now on.
