Description: JavaScript monitoring involves tracking the performance and errors in the execution of JavaScript code. This process is essential to ensure that web applications run efficiently and smoothly. Monitoring allows developers to identify performance bottlenecks, execution errors, and other issues that may affect user experience. Through monitoring tools, metrics can be collected on load times, resource utilization, and error frequency, providing a clear view of application behavior in real-time. Additionally, JavaScript monitoring is not limited to error detection but also includes overall performance analysis, enabling developers to optimize their code and improve application efficiency. In an environment where user experience is paramount, monitoring becomes an indispensable practice to maintain the quality and functionality of modern web applications.
