Hello World

Hello World: Basic Coding Example for Programming Languages

Hello World is a basic coding example used to demonstrate the simplest functionality of a programming language. It displays the phrase “Hello World” to indicate the code is working properly.

What is Hello World?

Hello World is one of the first programs nearly all developers create when learning a new programming language or framework. It is a very basic example that displays the text 'Hello World' to the screen or console. The purpose of Hello World is to:

• Verify the development environment is set up properly (compiler, SDKs, etc).
• Demonstrate the most basic syntax and structure of a programming language
• Ensure functionality works and output displays correctly
• Provide a starting point to build more complex programs

Hello World does not demonstrate any real-world functionality beyond displaying Hello World. However, it serves an important purpose as the most basic sanity check that a developer's tools are connected properly before writing more meaningful code. Nearly all coding books, tutorials, and courses begin with some variation of Hello World.
