Important Interview Questions For The Position Of Front-End Developers

Here are some of the most common interview questions for the position of front-end developers that you should prepare for:

Technical Questions

Q.1 Despite the fact that the front-end web development occupies a significant place in the success of many modern web projects, why it still faces challenges?

Front-end developers deal with designing, writing, and modification of sites, apps, and portals by means of HTML, CSS, JavaScript, and react-type frameworks like React in their everyday work. They stay with the product and design teams to put in place easy-to-understand, smooth, and user-friendly interfaces and experiences.

Q.2 What is different with front-end development today? What are the skills front-end developers are required to master?

Q.3 What are some ways to maximize the effectiveness of a website, can you tell me?

Improving performance assures you minify the code, lazy loading compress components, optimize images, reduce HTTP requests, cache assets at the edge of the CDN, remove the unused code, take service workers for offline space, use browser storage efficiently, and profiling regularly by lighthouse/WebPageTest to solve your bottlenecks.

Q.4 Accessibility of the websites remains to be a big challenge. Therefore, how can you make the websites accessible?

Improvement of accessibility is connected with adding the ARIA roles in the right way, making sure that the distinction ratio is adapted for better readability of your text, providing an image-alt text, creating a sense of logical information’ hierarchy by giving pages, giving pages orientation options with keyboard navigation or focus states, accommodating the users with color blindness, and testing extensively with the assistive apparatus.

Q.5 Why is React a well-liked option for front-end development nowadays?

Not only React possess numerous advantages over other frameworks (superior rendering due to virtual DOM diffing algorithm, encourages modular and reusable architectural components that help scale the applications, and most ecosystem libraries are free and open source, updates could be managed smoothly due to unidirectional data flow, thus become more productive because of Hot Module Replacement feature), but React also enables web developers to build and develop highly powerful.

Q.6 Tell me how client-side and server-side rendering work?

Client-side rendering consists of the provision of just a basic HTML shell of the raw HTML that is then used by JavaScript execution on the browser to load the dynamic content. On the upside, server-side rendering is one of the benefits of such types of applications. The latter’s main characteristic is the generation of full HTML pages on the server. HTML pages are sent to the client app that loads faster initially, but later browser interactions may be slower.

Q.7 Instead of that, what are the primary pros of having effective source control systems, like Git?

Git helps in the contribution of code, records in the code source all the changes to keep the audit, allows to creation of branches that insulate when feature development has been newly added, supports regression rollbacks from the previous stable version, and does a code review with pull requests and integrates with the code host resources like Github or Bitbucket.

Q.8 First off, as a front-end developer, knowledge of how to up your SEO game is that you should read?

One of the main challenges was the perfect tuning of a huge e-commerce website for better performance. The research data showed that the speed had increased by 40% due to methods like code splitting, in-line CSS, GPU acceleration, and APP cache logic.

Q.5 Why dont you team up with developers and product managers while in front-end development?

I work as closely as possible with designers when it comes to a rough design sketch which is referred to as “wireframing”. As a result, I can be directly involved in the creative process and provide my feedback early.

I ditched it by utilizing under time-dependent conditions the approach to components render and by its implementation, I improved the performance through memoization.

Q.9 What were your tools for implementing front-end performance mechanisms such as code splitting in the previous projects?

Lags on the dashboard are the perfect example of the app’s weight problems for an e-commerce commerce marketplace platform. I practice code-splitting by dynamically loading dashboards only when users hit that path for that widget. This effort not only succeeded in reducing downtime by almost 35%, but the TTI also jumped by almost 35% as well.
