Catching up and having new experiences with these trends will help you take full advantage of the magical technology world and pull up your business.

1. Blockchain

Blockchain is a specific type of database which differs from a typical database in the way it stores information. Blockchains store data in blocks that are then chained together.

Blockchain is easy to record transactions and tracking assets in a business network. An asset can be tangible like a house, car, cash, land, or intangible like intellectual property, patents, copyrights, branding. Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved.

One of the most disruptive technologies of Blockchain is using the Cryptocurrency concept such as a cryptocurrency wallet and a cryptocurrency exchange supporting Bitcoin, Bitcoin Cash, and Ethereum which help prevent fraud in sensitive transactions. They also provide Bitcoin data charts, stats, and market information.

Some functions are likely to increase in 2021, including use within smart contract platforms. Put it simply, Blockchain provides a two-sided transaction event, each transaction is verified by a decentralized distributed network. It means you will definitely know what data is verified and clear. Some benefits that Blockchain offers in web development:

  • Reliability in providing accurate results without delays and errors
  • Support and powerful security help protect both business and user data

3. Big Data

Big data is a term that describes the large volume of data – both structured and unstructured – that inundates a business on a day-to-day basis.

It can be categorized as unstructured like information that is unorganized and does not fall into a predetermined model or format or structured like information already managed by the organization in databases.

  • Big data can be collected from publicly shared comments on social networks and websites, voluntarily gathered from personal electronics and apps, through questionnaires, product purchases, and electronic check-ins or findings from data analysis, from human resources and technology to marketing and sales.

  • The goal of big data is to increase the speed at which products get to market, to reduce the amount of time and resources required to gain market adoption, target audiences, and to ensure customers remain satisfied.

  • In general, having more data on customers (and potential customers) should allow companies to better tailor products and marketing efforts in order to create the highest level of satisfaction and repeat business.

  • Big data is still among the top trends and investment opportunities. In 2021, a significant part of the job is going to be carried out by the tools that process everything in memory right away instead of storing data after each calculation.

  • Big data is believed to use to facilitate climatic change research and search for new medical cures and used for more natural language processing and easier data governance. However, cybersecurity in this area will remain a challenge.

4. Artificial Intelligence (AI)

Artificial intelligence (AI) is a wide-ranging branch of computer science concerned with building smart machines capable of performing tasks that typically require human intelligence.

The goals of artificial intelligence include learning, reasoning, and perception.

Weak AI tends to be simple and single-task oriented, while strong AI carries on tasks that are more complex and human-like.

  • AI is still a top technology and will become more powerful, affordable, and widespread, and helps businesses and organizations provide more personalized experiences for customers. Some examples of AI: Siri, Self-driving cars, Robo-advisors, Chatbots, Netflix's recommendations,...

  • The applications for artificial intelligence are endless and the technology can be applied to many different sectors and industries. For instance, AI is being tested and used in the healthcare industry for dosing drugs and different treatments in patients, and for surgical procedures in the operating room

  • AI chatbots help millions of people and lots of businesses perform operations faster by using text or voice chats. No doubt whether the future of web development will support AI-powered chatbots.

  • AI assistants and bots can learn, collect data, or solve difficult issues and it is considered one of the most influential technologies that shape the future of web development. Thus, the community demand for AI-enabled communication will become more widespread in 2021.

AI is expected to gain traction in 2021 as well, given that companies with AI-driven capabilities are likely to succeed.

1. Javascript

JavaScript (JS) is the programming language for the Web that can update and change both HTML and CSS., used both on the client-side and server-side that allows you to make web pages interactive.

It is one of the easiest to learn languages and becoming more popular in demand especially for development beginners in 2021 and forward.

Some reasons for JS’s popularity:

  • Unifying all of web application development around a single programming language, instead of using different languages for server-side and client-side scripts.

  • Using only one programming language to talk to databases, make HTTP requests, generate dynamic content, and create interactive user experiences/interfaces. This led to the Rise of Web Applications.

  • It can be used in both the front-end and back-end of web development frequently updated with new versions.

  • JavaScript works with the document object model, or the DOM( a structure in the browser that displays web pages), to respond to user interactions.

  • Allow websites to have interactivity like scroll transitions and object movement fast that give a better user experience.

  • A wide range of frameworks and libraries are available that help developers create complex applications at a low cost. The application’s functionality can be augmented by importing libraries and frameworks.

In a 2020 survey, JavaScript was identified as the programming language of choice by 70% of respondents.
