Elm vs HTML5: What are the differences?

Introduction

Elm is a functional programming language that compiles to JavaScript and is used for creating web applications, while HTML5 is a standard markup language for creating web pages.

1. Language Paradigm: Elm follows a functional programming paradigm with immutable data and no side effects, making it easier to reason about and test code, while HTML5 is a markup language used for structuring content on web pages.

2. Static Typing: In Elm, static typing helps catch errors at compile time, ensures type safety, and aids in refactoring code, whereas HTML5 does not have static typing, leading to potential runtime errors due to incorrect data types.

3. Framework vs. Language: Elm is a complete language with its own syntax, standard library, and architecture for building web applications, while HTML5 is just a markup language and requires additional frameworks like CSS and JavaScript for interactivity and styling.

4. Virtual DOM: Elm utilizes a virtual DOM to efficiently update the user interface by calculating the minimum number of changes needed, improving performance, while in HTML5, developers manually manipulate the DOM with JavaScript, which might be less efficient.

5. Error Handling: Elm provides detailed error messages with suggestions for fixing issues, helping developers debug code more easily, whereas with HTML5, error handling is more generic, often requiring developers to inspect the browser console for specific issues.

6. Hot Module Replacement: Elm supports hot module replacement, allowing for live reloading of code changes in the browser without losing the application state, a feature not readily available in traditional HTML5 development environments.

In Summary, Elm offers a functional and statically-typed approach for building web applications, with a virtual DOM, detailed error handling, and hot module replacement support, while HTML5 serves as a markup language without the same level of type safety, ease of debugging, and advanced features.
