## What are Languages, Libraries, and Frameworks?
## Top front-end programming languages to learn in 2024
Before we explore the front end languages, libraries, and frameworks to learn in 2024, it is important to understand what they are and the differences between them.
Here are the front-end programming languages you should learn in 2024.
**Languages**
Languages are the core programming languages that developers use to write code. They have defined syntax, semantics, and rules for writing instructions that computers can execute and understand. Examples include:
For web front-end development:
- JavaScript
- TypeScript
- Dart
- Kotlin
**Libraries**
Libraries are collections of pre-written code that developers can use to perform specific tasks. They save time and improve productivity because developers don’t have to write code from scratch. Libraries extend the functionality of a programming language by providing functions, methods, and classes that can be imported and used. Examples include:
- React
- Anime.js
- Chart.js
- JQuery
**Frameworks**
Frameworks are more comprehensive than libraries as they provide a structure or skeleton with sets of rules for building applications. They enforce architecture and offer tools, libraries, and components to streamline developments. Examples include:
- Vue
- Angular
- Flutter
The major differences are that languages are used to write code, libraries provide reusable functions, and frameworks offer a structured approach to developing applications.
These are the best front-end languages you should learn in 2024:
**For web front-end development**:
- HyperText Markup Language (HTML)
- Cascading Style Sheet (CSS)
- Cascading Style Sheets (CSS)
- JavaScript
- TypeScript
For mobile front-end development:
**For mobile front-end development**:

## Front-end programming languages for web development
### HyperText Markup Language (HTML)
Web development involves building websites, web applications, and web services that users interact with through web browsers. Front-end development focuses on the user interface (UI) and user experience (UX) aspects of web applications, ensuring that the content is visually appealing, interactive, and responsive.
HTML serves as the backbone for building all web pages. It defines the structure and layout of content within a web browser, allowing for the display of text, images, videos, and more that users interact with. HTML is beginner-friendly, supported across multiple browsers, and fundamental to web development.
HTML is the standard markup language for creating web pages. It defines the structure and layout of content within a web browser, allowing for the display of text, images, videos, and more that users interact with. HTML is beginner-friendly, supported across multiple browsers, and fundamental to web development.
HTML depends on languages like CSS and JavaScript to achieve full functionality, and it is mostly limited to web-based projects. Beyond being the backbone of web applications, it also plays an integral role in improving application accessibility, enhancing search engine optimization (SEO), and enabling assistive technologies to interpret and present content accurately.
**Why is it important**
HTML depends on languages like CSS and JavaScript to achieve full functionality, and it is mostly limited to web-based projects.
- HTML is the foundational language for creating web pages.
- It defines the structure and content of the web pages.

CSS plays a crucial role in determining the appearance and organization of web content. When used in conjunction with HTML, it enhances the appearance and layout of web pages, enabling the creation of responsive designs that adapt to various screen sizes. CSS handles colors, fonts, spacing, and more, allowing developers to create visually appealing user interfaces.
CSS has powerful styling options, is easy to start with, and has a great ecosystem of libraries and frameworks like Tailwind CSS, Bootstrap, Foundation, etc., to build aesthetically pleasing user interfaces.
Despite advancements in web technologies, CSS remains a powerful styling tool that is easy to start with. It has a robust ecosystem of libraries and frameworks, such as Tailwind CSS, Bootstrap, and Foundation, which facilitate the creation of aesthetically pleasing user interfaces.
**Why is it important**
