In 2023, there are several opportunities to learn for free. Websites such as Coursera, Khan Academy, and Udemy provide a diverse range of online courses in areas ranging from computer science to humanities. YouTube is another portal that offers free educational videos and courses.
Furthermore, many colleges and educational institutions have open-access programs that provide free access to educational information such as lectures and textbooks. Public libraries also have instructional resources and e-books available, and many groups conduct free workshops and webinars.
With so much material available, anyone in 2023 can continue to learn and acquire new talents without breaking their wallet.
These are the best routes for learning for free in 2023:
- HTML & CSS
- JavaScript
- Git & GitHub
- React
- SQL
- Blockchain
- Web3
1) HTML & CSS
The primary tools for producing websites are HTML (Hyper Text Markup Language) and CSS (Cascading Style Sheets). HTML is used to structure content on a webpage, such as text, graphics, and links. CSS is used to style and layout elements such as font size, background colour, and layout.
HTML tags define a webpage’s structure, whereas CSS rules govern its appearance. They form the foundation for developing dynamic, interactive, and visually appealing websites. There are several free internet resources, such as tutorials, movies, and code examples, to help you learn HTML & CSS and begin developing your websites.
2) JavaScript
JavaScript is a dynamic, high-level programming language that is commonly used for front-end web development. It enables the creation of interactive and dynamic web pages with features like drop-down menus, pop-ups, and animated effects. JavaScript can also be used for server-side development in conjunction with frameworks such as Node.js.
It is a necessary ability for modern web programming, and all major browsers support it. There are numerous free tools accessible to learn JavaScript, including online tutorials, video classes, and interactive coding challenges. Begin with fundamental concepts such as variables, data types, loops, and functions before progressing to more complex topics such as event handling, async programming, and working with APIs.
3) Git & GitHub
Git is a distributed version control system that is used to track file changes and coordinate work among several people. GitHub is a web-based platform based on Git that offers functionality including bug tracking, project management, and team communication. You can use Git to track all changes to your code, revert to earlier versions, and collaborate on projects with others in a decentralized fashion.
GitHub makes hosting and managing Git repositories, collaborating with others, and sharing your work with the world simple. Start with Git basics like cloning repositories, creating branches, and committing changes, then move on to GitHub features like pull requests, problems, and wikis. There are numerous free materials available online, such as tutorials, movies, and articles.
4) React
Facebook created and maintains React, a JavaScript library for creating user interfaces. It enables efficient and fast rendering by providing a declarative way to construct UI components and manage their state. Because React enables for the creation of reusable UI components and quick user interface updates, it is a popular choice for developing single-page applications.
Start with the fundamentals of React, such as components, state, and props, and then on to more complex subjects such as hooks, context API, and Redux. There are various free online tools available to help you get started with React programs, such as online tutorials, video courses, and interactive code challenges.
5) SQL
SQL (Structured Query Language) is a domain-specific language that is used to manage and manipulate data in relational databases such as MySQL, Oracle, and Microsoft SQL Server. SQL is used for database functions such as adding, updating and retrieving data.
It supports querying data with SELECT queries, filtering data with WHERE expressions, and aggregating data with GROUP BY statements. Begin by learning the fundamentals of SQL, such as data types, SELECT statements, and data filtering, before progressing to more complex topics such as inner and outer joins, subqueries, and transactions.
To get started with SQL, there are numerous free resources available online, including tutorials, video courses, and interactive coding challenges.
6) Blockchain
Blockchain is a distributed ledger technology that is used for secure and transparent record-keeping. It was created for Bitcoin, but its possible applications include finance, supply chain management, and digital identity.
A blockchain’s key characteristic is that data is saved in a chain of blocks, and once recorded, data cannot be updated without the consensus of network participants. Begin with learning the fundamentals of blockchain, such as how transactions are processed and added to the blockchain, the role of nodes, and the concept of consensus.
There are various free online tools accessible to assist you to get started with blockchain technology, such as online courses, tutorials, and video lectures.
7) Web3
Web3 is a blockchain-based decentralized internet that gives people more control over their data and online identities. It intends to replace the current internet’s centralized, server-based design with a more open, secure, and transparent network.
Decentralized apps (DAPPs), smart contracts, and digital wallets that store cryptocurrencies and other assets are key components of Web3. Begin by learning the fundamentals of blockchain technology, then move on to decentralized apps, smart contracts, and digital wallets.
