Error detection and best practices

In this subject, participants learn techniques for detecting errors and debugging JavaScript code. The course begins with identifying and avoiding common errors in JavaScript programming. Participants will learn how to recognize and prevent typical problems in order to increase the stability and reliability of their applications.

Another important aspect is debugging methods and tools. Participants will learn how to apply effective debugging techniques to quickly identify and fix errors. This includes the use of integrated development environments (IDEs) and browser developer tools that offer special debugging functions. Practical debugging exercises help participants to apply what they have learned in real-life scenarios and improve their debugging skills.

Best Practices

The second part of the course focuses on the application of best practices in JavaScript programming. Participants will learn best practices for code organization and structuring to write clean, maintainable and scalable code. This includes techniques for modularization and meaningful naming of variables and functions.

Another focus is on refactoring code. Participants will learn how to restructure existing code to improve readability and efficiency without changing functionality. These techniques are crucial for the long-term maintenance and extensibility of software projects.

In addition, security aspects in JavaScript will be covered. Participants will learn how to identify and fix security vulnerabilities to protect their applications against common threats such as Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF).
