Skills to Look for in a Front-End Developer
When looking for front-end developers, you should know their responsibilities and be aware of the tools they use in their works. Here is a list of their chief duties and the tools they use to create front-end layers of applications.
1. Creation of an application layout
Application layout includes a compelling display of application content to end-users with some styling elements. For this, front-end developers use two primary programming languages – HTML and CSS.
2. Adding animations, user interactions, and other elements
Although HTML and CSS work great for static web page elements, front-end developers should know JavaScript. This programming language makes web pages more interactive, so preferred by end-users. It includes embedded video players, moving menus, interactive maps, pop-ups, animations, etc.
3. Writing a frond-end code
Front-end developers should try to write clean and lean codes. It is because developers can later reuse the code for building other applications. Also, it can be shared with other front-end developers if needed. It will speed up the application building process.
4. Application optimization and scalability
To ensure great application performance, developers need to monitor how their codes and app systems function. For instance, the application starts and works quickly, has great design, has no major issues, and more. Another vital aspect is app scalability, which denotes that an app has the potential to grow and handle more operations without any delays.

Use of frameworks – The widely used frameworks include Backbone.js, AngularJS, jQuery, React.js, Vue.js, Bootstrap, etc.
Use of AJAX – These development techniques allow sending asynchronous requests to the server.
Responsive design – This versatile web technology allows running web applications on various devices without any design flaws.
Test-driven development – With this, coding, testing, and design are performed with the development process to avoid functionality blocking errors and reach the deadline.
