Types of Front-End Developers

The title of a developer directly depends on the name of the master framework or technology.

We’ve compiled a comparison table showcasing the development activity across various front-end frameworks for the first month of 2024:

Angular Front-end developer

Angular emerges as the clear winner, boasting a significantly larger number of unique contributors, approximately six times more than React. Additionally, Angular demonstrates an impressive volume of lines of code added and removed, alongside addressing a substantial number of reported issues, with 180 closed issues during this period. This proactive approach to bug fixing and continuous improvement highlights Angular’s robust development ecosystem.

React Front-end developer

React secures the second position, despite having a smaller contributor base. With 14 unique authors, React showcases an efficient review and integration process, evidenced by 112 merged pull requests.

Svelte and Vue.js Front-end developers

Common Front-End interview questions

React Front-End developer interview questions

Q1. What are the peculiarities of React?
А1. The main peculiarities of React are:

  • use of virtual DOM;
  • component approach;
  • use of JSX.

Q2. What is JSX?
А2. JSX – is an acronym for JavaScript XML. This is the type of file that uses the expressiveness of JS together with HTML syntax similar to a template. It facilitates understanding an HTML file.

Q3. How are forms created in React?
А3. Forms in React are similar to forms in HTML. However, in React, the state is contained in the property of the state component and is updated only through setState (). Thus, elements can’t directly update their states and their passing is processed by the JavaScript function.

Angular Front-End Developer interview questions

Q1. What are components, and what are they required for?
А1. In Angular, one component contains other components, resulting in a structure resembling a tree consisting of building blocks enabling user interface creation. Components in Angular can be treated as basic building blocks of the whole user interface. Every component has its intent inside an application. For instance, a blog feed is one component, and a read post is another component. Components are motion-sensitive and respond to user actions, including click, open, minimize, maximize, etc.

Q2. What is the difference between a component and a module?
A2. Components control HTML itself and visualization. Modules consist of one or several components and serve to determine what is in the application.

A module is a kind of box containing all the parts of the application, while components are building blocks containing the functional elements of the same application.

Q3. What is the difference between @Component and @Directive?
A3. Directives assign behavior patterns (color, size, styles, etc.) however at the same time they don’t create their own functionality and structure for the application. They work within the component and the component in turn creates the structure where template behavior can be assigned through a directive.

Vue Front-End developer interview questions

Q1. How can we get request parameters in Vue.js?
А1. You have access to the $route objects from your components that provide what is needed.

Q2. What are Vue.js components?
А2. Components – is one of the most powerful functions of Vue.js. Vue components have customizable elements that help to extend basic HTML elements to encapsulate repeatedly used code.

Q3. How can two-way binding be created in Vue.js?
А3. In Vue.js, the v-model directive is used to create two-way bindings.
In two-way binding, the data or model is bound to the DOM, and the DOM is bound back to the model.

Questions to be asked are mainly determined by the seniority and professional level. More detailed information on how to interview React and Angular developers is provided in our articles How to Hire React JS developer, How to Hire Angular developer.
