Not Planning Before Coding: Jumping straight into coding without a clear plan or understanding of the project requirements can lead to inefficient code and wasted time.

Ignoring Responsive Design: Failing to design websites to be responsive across various devices and screen sizes can result in poor user experience and reduced accessibility.

Overlooking Browser Compatibility: Not testing websites on different browsers and devices can lead to unexpected layout issues and functionality discrepancies.

Neglecting Performance Optimization: Ignoring factors such as image optimization, code minification, and caching can result in slow-loading websites, impacting user engagement and SEO.

Using Deprecated or Outdated Technologies: Relying on outdated or deprecated technologies and practices can lead to security vulnerabilities and compatibility issues in the long run.

Not Using Version Control: Failing to use version control systems like Git can make it difficult to track changes, collaborate with others, and revert to previous versions when needed.

Copying and Pasting Code Without Understanding: Blindly copying and pasting code from tutorials or Stack Overflow without understanding how it works can lead to bugs and hinder learning.

Overcomplicating Solutions: Beginners often overcomplicate solutions by using complex code when simpler approaches would suffice. Keeping code concise and understandable is essential for maintainability.

Ignoring Accessibility: Neglecting accessibility considerations such as proper semantic markup, keyboard navigation, and screen reader compatibility can exclude users with disabilities from accessing the website.

Not Seeking Feedback: Failing to seek feedback from peers or more experienced developers can limit opportunities for learning and improvement. Regularly seeking feedback helps identify areas for growth and refinement in coding practices.
