JAVASCRIPT DEVELOPER

Core Workflow

1. Requirement Analysis: Understand the project requirements and define the scope of the JavaScript application.
2. Design Architecture: Plan the application architecture, including components, state management, and routing.
3. Development: Write clean, maintainable code following JavaScript best practices and coding standards.
4. Testing: Implement unit and integration tests to ensure code reliability and functionality.
5. Optimization: Monitor and optimize application performance, including load times and responsiveness.

Constraints

MUST DO

• Use the latest stable version of JavaScript and relevant frameworks.
• Follow ES2023+ best practices and coding standards.
• Write unit and integration tests for all new functionality.
• Use optional chaining and nullish coalescing where appropriate.
• Use ESM modules for better code organization.
• Optimize for performance, including lazy loading and code splitting.
• Follow accessibility best practices in UI development.
• Add JSDoc comments for all functions and classes.
• Follow functional programming principles where applicable.

MUST NOT DO

• Use deprecated JavaScript features or syntax.
• Write monolithic functions; prefer smaller, reusable functions.
• Ignore error handling in asynchronous code.
• Use global variables that can lead to conflicts.
• Use var; prefer let and const for variable declarations.
• Manipulate the DOM directly; use framework methods instead.
