The Node js Developer Roadmap for 2021 by Mohit

Compared to MongoDB, it’s a bit more difficult to learn as you need to learn about SQL as well. So after learning JavaScript and a framework, you need to practice by building projects. Besides learning the basics of React, you also want to pay attention to how State is managed in React applications and how Forms work in React. But personally, I would continue by learning at least one framework.

  • You can then load that website through a browser (like Chrome, Firefox, or Safari) on your computer or your phone.
  • React may not be the fastest library out there, but in terms of the ecosystem, overall usage experience and benefits, it is still one of the greatest.
  • “Front end” means that you’re dealing mainly with the client side.
  • When I started learning Java, I started with books which were very hard to read, lengthy and boring but they had computer programs which I can copy and run.
  • Always create projects, no matter if it’s small, but start creating projects and host them on GitHub.
  • If you combine this with his front end map, you get a pretty good path to becoming a full stack developer.

In such situations, a map or a guide becomes your invaluable companion, aiding your journey. If you have a contact form on your website, you could build the form so that every time someone submits the form, their data is saved onto your database. Nowadays there are also serverless architectures, which is a more decentralized type of setup. This type of application splits up those components and leverages third party vendors to handle each of them. Vue is a newer framework created by Evan You, a former Angular developer. While it is smaller in use than React and Angular, it is growing quickly and is also considered easy and fun to use.

Once you are familiar with JavaScript basics, the next step is to understand JavaScript variables (containers for values) that help in storing and representing information. A JavaScript developer is someone responsible for designing and implementing the front-end logic to define the visual elements’ behavior in a web app. Whether we talk about small startups or large-scale enterprises, most require a JavaScript developer to work on their website or web app. JavaScript is the most used language among worldwide developers as of 2022, with more than 65% of respondents stating they have used JS, followed by HTML/CSS, SQL, Python, TypeScript, and Java. Next, we have NPM which is a package manager for JavaScript programming. This allows you to install different packages on your machine quickly.

Redux-thunk and redux-saga were created to solve those problems. They may take some time to understand as they require understanding of functional programming and generators. Over the years, new view libraries that are even more performant than React have emerged. React may not be the fastest library out there, but in terms of the ecosystem, overall usage experience and benefits, it is still one of the greatest. Facebook is also channeling efforts into making React even faster with a rewrite of the underlying reconciliation algorithm. The concepts that React introduced has taught us how to write better code, more maintainable web apps and made us better engineers.

This section focuses on the analysis choices that are made in undertaking an analytics initiative and the choices made in the type and complexity of analysis. The essence of this section is to provide coalitions the opportunity to improve the analysis of the outcomes in their initiative. Generally speaking, higher levels of analysis (level 2 or 3) are preceded by higher levels of preparedness, although it is possible for highly sophisticated analysis to take place in isolation.

Npm (Node Package Manager) is a package manager for the JavaScript programming language maintained by npm, Inc. Git is software for tracking changes in any set of files, usually used for coordinating work among programmers collaboratively developing source code during software development. Its goals include speed, data integrity, and support for distributed, non-linear workflows (thousands of parallel branches running on different systems).

Browser used to receive HTML from the server and then render it. When page refreshes or user navigates to different page, the servers used to send new HTML. Apart from that, accessibility is also an important thing to learn in HTML to make sure web-apps are accessible to everyone through different devices. Cascading Style Sheets are a simple way to add styles, like fonts and colors to documents.

Node.js has been one of the biggest game-changer since its release, bigger companies like Uber, Medium, PayPal & Walmart switched their tech stack to Node.js. You can make really powerful applications with Node.js such as real-time tracking apps, video and text chat engines, social media apps, etc. And learning Node.js is becoming one of the hottest skills for developers, the roadmap that I have prepared is based on how I learned it with my own experience and tips.


With React Native, you use native UI controls and have full access to the native platform. Types also serve as a form of documentation for your code and improves the readability of your code. As a code base grows larger, we see the importance of types as they gives us greater confidence when we do refactoring.

Both help in optimizing the web app’s performance, making it yet another concept to clarify to become a successful JavaScript developer. Data structures represent the format used to manage, organize, and store data to boost efficient modification and access. Put simply, data structures are collections of data values, the functions that can be applied to them, and their relationships with each other.

Therefore, don’t forget to check out my Youtube Channel and DevChallenges Learn. Other less important topics when you are just getting started are Regular expressions, Web Components, and Websockets. But here I want to talk about how to use Figma as a developer.

At the lowest level of actionability, there is a lack of evidence and work accomplished, warranting serious concerns for the coalition to move forward. Given the missing evidence, actionability at this level would be compromised if gaps are not addressed. There are serious concerns with the efficacy of this part of the plan, and evidence to demonstrate its full development is limited.

For the most part, using ESLint is as simple as tweaking a configuration file in your project folder. There’s nothing much to learn about ESLint if you’re not writing new rules for it. Just be aware of the errors when they surface and Google it to find out the recommended style. The creator of Redux, Dan Abramov, has taken great care in writing up detailed documentation for Redux, along with creating comprehensive video tutorials for learning basic and advanced Redux.
