What is front-end development?

Frontend development primarily focuses on user experience. Using related coding and design techniques, you as a front-end developer create the elements of the application that end users can directly access, with the goal of rendering the entire interface elegant, easy-to-use, fast, and secure, which promotes user engagement. and interactions.

As part of creating an engaging user interface, leading app development often focuses on specific design elements such as text colors and styles, images, charts and tables, buttons, and overall color schemes. These elements play a vital role in increasing the visual appeal and user-friendliness of the application.

Front End Development: The Complete Guide includes various interactive elements such as sliders, pop-up forms, and custom interactive maps. An essential part of a front-end application are navigation menus that guide application users and improve their overall experience and interaction with the website or application. Creating intuitive and user-friendly navigation menus is a key skill for front-end developers.

Front-end developers require a specific skill set to effectively create user interfaces. This includes knowledge of coding languages ​​such as HTML, CSS and JavaScript, as well as a good understanding of CSS preprocessors such as Sass and Less. In terms of career requirements, aspiring front-end developers often study computer science or a related field, although this is not always a mandatory requirement. Strong fundamentals and knowledge of coding languages ​​such as HTML, CSS, JavaScript and increasingly jQuery are essential.

Additionally, it is beneficial to understand server-side CSS processing techniques and their applications in web development. They should also be proficient in TypeScript, a superset of JavaScript that adds static typing capabilities to the language.

Thanks to the latest design trends and front-end technologies, you can create increasingly sophisticated designs and interaction patterns. At the same time, however, there is more complexity, so much so that front-end web application development has become a specialized field that requires deep expertise.

The main trend in front-end development in recent years is the growth of applications for mobile and smart devices, where users access applications from an increasing number of devices with different screen sizes and interaction options. As a result, front-end developers must ensure that their application provides a consistent, high-quality user experience for all devices and usage scenarios. This is a daunting challenge.

Those that interact with users are on the front end; those that serve the technology are located in the back end, also called the data access layer. The back provides a means to support the front.

Back-end development focuses on what goes on behind the scenes, whereas front-end development focuses on what happens in front of the user. Front-end development is often considered to be technically easier compared to the complexity of back-end development, which requires a solid command of programming languages, data structures and algorithms (DSA), and data management skills.

Here are the key differences between front-end and back-end software development:

Back-end development is the process of creating components to run an application behind the scenes. Examples include components for data storage, infrastructure, integration with external systems, and code written in one or more programming languages. Users do not have access to the backend. Examples are user interfaces, buttons, user input data, web pages, and user experience (UX) features. Frontend focuses on meeting user requirements and providing a positive user experience. This approach involves breaking up front-end application development into smaller, more manageable chunks for better scalability and maintainability. In addition, frontend developers must also master code testing and analysis tools to ensure application quality and performance.

Programming languages ​​for front-end web development

HTML HyperText Markup Language (HTML), which defines the structure and meaning of web content, is the building block for front-end web development.

CSS Cascading Style Sheets (CSS) is a standard language that specifies how to display HTML content: fonts, foreground and background colors, etc. You can use CSS to control the layout of your design and its components for different devices, such as desktop computers, tablets, and smartphones. Examples of components are header, body, footer, content, asides, and sections.

JavaScript JavaScript (JS) extends the functionality of web pages beyond HTML and CSS. Through JS:

Web pages can dynamically refresh and respond to user actions without page reloads or other changes. You can model animated user interface components such as popups, image sliders, and extensive navigation menus.

Average salary for front-end web developers

In the United States, front-end developers earn an average annual salary of $90,345, according to Glassdoor. This amount includes a base salary of $83,119 and additional compensation of $7,226, which may come from a variety of sources such as profit sharing, commissions or bonuses. Factors such as education, work experience, and professional certifications can affect the overall salary range of front-end developers.

Bootstrap Bootstrap, a popular open-source framework for developing responsive and mobile websites, offers CSS and JavaScript-based templates that include components such as navigation bars, progress bars, thumbnails, and drop-down lists that you can incorporate into your web pages.

Bootstrap implements responsive images through inline code that automatically resizes them according to the current screen size. With JQuery plugins in Bootstrap, you can also create and deliver interactive solutions for modal popups, image carousels, and transitions.
