Front-end Development is the development or creation of a user interface using some markup languages and other tools. It is the development of the user side where only user interaction will be counted. It consists of the interface where buttons, texts, alignments, etc are involved and used by the user.
Languages for Frontend Development
Front-end is the part that is accessible to the user only, It should be self-explanatory and must be user-friendly and designed. so to achieve this we have some basic languages which can be used to create interactive web pages. These are the basic needs for the creation of a web page.
- HTML: Introduced in 1993 and now at HTML5, it is a core language for creating structured web content. It supports forms, tables, and other elements needed to organize information, and continues to evolve to help developers build interactive, accessible interfaces across platforms.
- CSS: CSS, introduced on 17 December 1996 and now at CSS3, stands for Cascading Style Sheets. It complements HTML by adding styling, managing colors, and enabling responsive designs. CSS helps developers create visually appealing, consistent layouts across devices and screen sizes.
- JavaScript: ECMAScript, introduced on 4 December 1995 and now at ECMAScript 2022, is a lightweight, cross-platform, single-threaded language. It enables dynamic updates and event handling in web development, making it key for building interactive and responsive user interfaces.
Frontend Development Frameworks
Frameworks add more features to their respective languages. Frameworks provide extra features, structure, fast reloading, and many more things so that developers can develop a SPA(Single page application) easily. Some of them provide inbuilt functions or pre-defined components so that developer can directly use those in their projects.
- jQuery : Introduced in August 2006 and now at version 3.7.1, it is an open-source JavaScript library for DOM manipulation, CSS editing, event handling, AJAX, and animations. It streamlines web development and enhances interface responsiveness.
- React : Introduced in May 2013 and now at version 18.2.0, it is a JavaScript UI library for building SPAs. It focuses on component-based development, efficient state management, and uses a virtual DOM for fast updates. React simplifies complex UI tasks, promotes reusability, and is widely used in modern web development.
- Angular : Introduced on October 20, 2010 and now at version 17.0.3, it is an open-source JavaScript framework by Google that follows the MVC pattern. It is used for building SPAs, enabling fast page updates and providing a modern, modular structure for web development.
- Vue.js : Introduced in February 2014 and now at version 3.3.0, it is a JavaScript framework similar to React for building UI layers. It offers reactive data binding, a component-based structure, Vue directives, and Vue Router, making it well-suited for dynamic, interactive web applications.
- Bootstrap : Introduced in August 2011 and now at version 5.3.2, it is an open-source front-end framework offering HTML, CSS, and JavaScript components. It includes a responsive grid system, pre-styled elements, and customizable themes and templates for fast web development.
Responsive Web Development
Specifies that web applications should be accessible on devices of various shapes and sizes, particularly crucial for mobile devices due to increasing traffic.
Methods for Achieving Responsiveness:
- Breakpoints: Web applications adjust width and height based on device characteristics to enhance user interaction.
- Flexible Images: Ensures images fit within device width, adapting using frameworks or raw CSS.
- Flexible Grids: CSS grids align layouts responsively to accommodate different device sizes.
- Media Queries: CSS tool defining responsive changes at specific points based on device characteristics. Query in CSS is also used to make web pages responsive. In that we describe what to change on specific point.
Frontend Security
Whenever we create any web page and there is a section for login or signup then there must be a security so that the password given by the user must be secured and can not be accessed by third party between the login session. so we must provide security to our web pages. same goes for the web pages where a payment statement or any other confidential data is transfered or stored.
These are the attacks that can make your web page more risky:
- DoS (denial of service) attacks: This attack is hard to handle because it comes from thousands of systems at once, slowing down your webpage. To prevent it, you can use a firewall or security services like Cloudflare.
- Preventing cross-site request forgery (CSRF): In this attack, the attacker inserts suspicious elements into your webpage to steal the token stored in your browser. Using that token, they can access your data and cause harm. It can be prevented by using secure token-generation methods like MD5 or SHA-256.
- Cross-site scripting (XSS) attacks: In this attack, the attacker replaces parts of your webpage with similar-looking components. For example, a user may click a submit button, but it secretly sends sensitive information to the attacker or downloads malware onto the system.
Why Learn Front-End Development?
Front-end development forms the foundation of user experience on the web, making it a crucial skill for aspiring developers. Mastering front-end techniques helps individuals to create visually appealing and interactive interfaces that engage users effectively. It helps to create responsive layouts which one can navigate seamlessly.
