What skills and tools should a JavaScript developer have?

When choosing a JavaScript developer, you should clearly understand what tasks he will perform on the project. It depends on what tools, frameworks and libraries he should be able to work with for the successful implementation of the product. We at AVADA MEDIA can cover any needs of our clients. Our staff employs more than 20 qualified specialists of the Middle and Senior level, whose stack includes most of the current technologies. Let's consider the main ones:

Vue.js

The progressive JavaScript framework is ideal for developing web applications and SPAs of any complexity. It allows you to create dynamic, high-performance interfaces that can send and receive requests from the server without reloading the page.

Due to its lightness and a large number of tools that speed up the work of specialists, Vue.js is also often used to create an MVP - a minimum viable product.

React.js

React.js is a JavaScript library created by Facebook developers. It uses a virtual representation of the DOM to effectively update the user interface, thereby ensuring high performance and responsiveness of the client side of sites and web applications.

React is based on a component architecture, which allows you to break the user interface into small independent components. This makes the code more modular and makes it possible to reuse already existing components, which significantly accelerates the speed of the technical implementation of the UI.

Node.js

This JavaScript runtime is based on Google Chrome's V8 engine, which extends the language's capabilities and makes it applicable for server-side application development. One of the main advantages of Node.js is its asynchronous input/output model. It allows you to handle a large number of simultaneous connections and update data in real time without blocking the execution thread. This provides high code performance that can compete with many server-side languages such as PHP and Python.

Because of its asynchrony, Node.js is often used to create chats, games, data streaming, and other solutions that require instant processing of a large number of user requests.

What other tools will be needed

Also, for effective work and interaction in a team, a JavaScript developer must have a set of additional tools:

• HTML and CSS . These tools determine the structure and style of web pages, so a JavaScript developer must be able to work with them to implement full-fledged application interfaces. In addition, JS is used to manipulate the DOM, which represents the structure of an HTML document, so knowledge of HTML is necessary for an expert to interact with elements effectively.
• Git . The version control system helps to save created projects, share source code and work effectively in a team.
• Ajax/Fetch API . Ajax makes asynchronous requests to the server to quickly send and receive up-to-date data. The Fetch API essentially performs the same task, and is a newer implementation of the approach.
• SEO tools . In addition to writing code, a JavaScript developer optimizes website pages for search engines and must be able to work with SEO tools. With a competent approach at the stage of resource development, you will be able to save a significant part of the marketing budget in the future.
• RESTful . Even if a JavaScript developer will work on the front-end of your product, he must know how the data exchange protocols between the client and the server are implemented. At a minimum, he should have a clear understanding of what methods can be used to query the server and what statuses can be returned.

How to correctly check a developer's JavaScript competence?

Before connecting a JavaScript developer to a project and trusting him to perform real tasks, you should make sure of his competences. This can be done in different ways:

• Explore his previous projects. Ask the candidate to provide their code and project portfolio. Analyze the quality of the code, the patterns used, the structure of the projects and their performance. Also, pay attention to whether the specialist has experience in your niche.
• Conduct a technical interview. Ask the candidate to answer technical questions about JavaScript and the frameworks you plan to use in your project. You can start with basic things like syntax, functions, objects, data structures, also ask about asynchronous programming, DOM, event handling and algorithms.
• Architectural issues. Discuss with the candidate the architectural solutions they used to build a large web application. This may include questions about project structure, use of frameworks, state management, scalability, etc.
• Code review. Ask the candidate to go through a code review where they have to analyze and fix another developer's code. This will help gauge his ability to read and understand other people's code, as well as his ability to provide constructive feedback.
• Practical task. Ask the developer to perform a real-world task on the JavaScript or JS framework you plan to use in your project to evaluate how quickly and efficiently the candidate works in practice.

At the stage of hiring a JavaScript programmer, you should clearly understand that this is exactly the person you were looking for for your project. Our developers at JS are ready to pass any technical interview and confirm their qualifications, just make an appointment.
