Want to become a Front-End Developer?

Here’s a roadmap with essential skills & concepts to learn:

1. Core Web Development

HTML & CSS: Master the basics and advanced features (e.g., Flexbox, Grid, animations, responsiveness).

JavaScript: Understand ES6+ syntax, DOM manipulation, events, asynchronous programming (Promises, async/await).


2. CSS Frameworks & Preprocessors

CSS Frameworks: Learn Bootstrap, Tailwind CSS, or Materialize for quick, responsive design.

CSS Preprocessors: Sass or LESS to write efficient, reusable CSS with variables and functions.


3. JavaScript Frameworks & Libraries

React: Widely used for component-based architecture. Learn hooks, context, and basic state management.

Vue.js or Angular: Understand their core concepts if you need to adapt to other frameworks.


4. State Management

Redux / Context API: Manage application state in larger applications.

MobX, Zustand, or Recoil: Alternatives to Redux, depending on the project.


5. API Integration & Async Operations

REST APIs & GraphQL: Fetch and update data from servers using Axios or Fetch API.

Async Operations: Work with asynchronous data flows using Promises, async/await, and Observables.


6. Component-Driven Development

Storybook: Develop and test components in isolation.

Atomic Design: Break down UIs into small, reusable components.


7. Testing & Debugging

Unit Testing: Use Jest or Mocha for JavaScript testing.

Component Testing: Use tools like React Testing Library or Enzyme.

End-to-End (E2E) Testing: Cypress or Playwright for simulating real user interactions.


8. Progressive Web Apps (PWAs)

Offline Capabilities: Caching and Service Workers to make apps offline-friendly.

Web App Manifest: Make web apps installable on mobile devices.


9. Performance Optimization

Lazy Loading: Load only the necessary resources.

Code Splitting: Break down code for faster loading (Webpack, Vite).

Image Optimization: Use modern formats (WebP), and implement responsive images.


10. Web Accessibility

WAI-ARIA: Accessibility standards to make your app usable for all users.

WCAG: Follow Web Content Accessibility Guidelines.


11. Responsive & Adaptive Design

Media Queries: Write responsive layouts to suit various devices.

Adaptive Design: Develop different designs for mobile, tablet, and desktop.


12. Version Control & Collaboration

Git: Learn the basics of version control.

GitHub/GitLab: Collaborate with other developers and manage repositories.


13. Deployment & DevOps Basics

CI/CD: Automate build and deployment pipelines with GitHub Actions or GitLab CI.

Hosting: Deploy on Netlify, Vercel, or AWS Amplify.


14. Security

Secure APIs: Understand Cross-Origin Resource Sharing (CORS) and CSRF protection.

Authentication: Learn about OAuth, JWT, and cookie/session management.

Leetcode patterns you should definitely checkout to Learn DSA(Java) from scratch

1️⃣ Arrays: Data structures, such as arrays, store elements in contiguous memory locations. They are versatile and useful for a wide variety of purposes.
LeetCode Problems:
• Search in Rotated Sorted Array (Problem #33)
• Product of Array Except Self (Problem #238)
• Find the Missing Number (Problem #268)

2️⃣Two Pointers: In Two Pointers, two pointers are maintained in the collection and can be manipulated to solve a problem efficiently.
LeetCode problems:
• Trapping Rain Water (Problem #42)
• Longest Substring Without Repeating Characters (Problem #3)
• Squares of a Sorted Array (Problem #977)

3️⃣In-place Linked List Traversal: As an explanation, in-place traversal is a technique for modifying linked list nodes without using extra space.
LeetCode Problems:
• Remove Nth Node From End of List (Problem #19)
• Reorder List (Problem #143)

4️⃣Fast & Slow Pointers: This pattern uses two pointers to traverse a sequence at different speeds (fast and slow), often used to detect cycles or find a specific position in the sequence.
LeetCode Problems:
• Happy Number (Problem #202)
• Subarray Sum Equals K (Problem #560)
• Intersection of Two Linked Lists (Problem #160)

5️⃣Merge Intervals: This pattern involves merging overlapping intervals in a collection, often used in problems dealing with intervals or ranges.
LeetCode problems:
• Non-overlapping Intervals (Problem #435)
• Minimum Number of Arrows to Burst Balloons (Problem #452)
