Front-end developers use HTML to create the structure and content of a web page. They use HTML tags to define the different elements on a page and organize them into a logical hierarchy. Following this, the web browser interprets the HTML code to display the page. Without using HTML, the internet over the web as we know it today would not exist. By asking this question, the hiring manager wants to assess your familiarity with such systems and how you leverage them to streamline your work, manage code, and collaborate with other team members.

• “Hiring for skills is 5X more predictive of job performance than hiring for education and more than two times more predictive than hiring for work experience.”
• It’s important for a potential hire to understand that they need to stay up to date on the latest trends in order to be successful in their role.
• In addition to Git, front-end developers use CSS to alter the font, color, size, and spacing of text on a web page.
• This is a critical skill for any front end developer, so the interviewer is looking to make sure you have the necessary knowledge and experience.

The virtual DOM is a programming concept used by libraries like React to improve rendering performance. It’s an abstraction of the real DOM that represents the UI elements as a lightweight, in-memory data structure. Single-page applications (SPAs) are web applications that load a single HTML page and dynamically update content as the user interacts with the app. The page doesn’t reload during navigation, and data is often fetched asynchronously.

Commonly Asked Interview Questions for Frontend Developers

Most animations and transitions are brought into CSS through JavaScript; another way in which CSS, JavaScript, and HTML are so entwined. You might name an element in CSS and set its parameters with CSS only to process an animation with JavaScript. There are some built-in animations and transitions in CSS, but they tend to be fairly rudimentary. You will need to initiate event loops to scan for user behaviors like clicks. Talk about the steps you take to fix mistakes, such as undoing your changes or writing tests. Also, mention how you prevent yourself from making the same mistake twice, such as keeping better documentation.

Window.onload, on the other hand, is only invoked after the DOM is fully loaded and ready with all content, including images, scripts, and CSS. When one element’s layout, window size, or other properties are altered, the position of all subsequent elements changes as well. Load balancing is a way of allocating and processing requests across several devices rather than a single device. This guarantees that the load is distributed efficiently and does not rely on a single location. The element in HTML is used to tell the browser what version of HTML is being used in the page. Now that you know what types of questions you’ll face in your interview, you can begin to practice your answers.

What are the differences between CSS grid layout and CSS flexbox? When would you use each?

I also make use of CSS resets or normalizers to create a consistent baseline across browsers. Instead of confronting him directly, I initiated an open discussion during our stand-up meetings about the importance of adhering to timelines for successful project completion. I also implement structured data markup for rich snippets which can significantly improve click-through rates. Its easy learning curve and lightweight nature made it ideal for smaller scale projects.

Next, I refactored critical parts of the application using modern frameworks like React while ensuring backward compatibility. In today’s digital age, cyber threats are ubiquitous and can cause serious damage to an organization’s reputation and bottom-line. Understanding your familiarity with web security measures is a way for the employer to gauge your ability to design and implement secure and robust front-end solutions.

“Describe your workflow when converting a design mockup into a functional webpage.”

An interviewer may also ask questions about your experience with specific frameworks or libraries, such as React or Angular. Prepare your answer by reviewing courses, certifications, boot camps, and other educational experiences you’ve completed. How have you used the knowledge and skills you how to become a front end developer gained in each one to create better websites? You might also research various front-end developer news sources, influencers, blogs, podcasts, and schools to find additional resources to advance your skills. Examples include freeCodeCamp, Egghead, Codecademy, W3Schools, and front-endHappy Hour.

Since technologies change quickly, recruiters want to know that you’re up-to-date on the latest trends and can quickly learn any new technologies that may be necessary for the job.
