Chrome DevTools is a powerful set of debugging tools built into the Chrome browser. It provides developers with a range of features such as real-time editing, breakpoints, and performance analysis.
Visual Studio Code Debugger
1. Reproduce the Issue
The first step in debugging is to reproduce the issue or error. This involves identifying the steps or inputs that cause the error to occur. Once you can reliably reproduce the error, you can begin to debug it.
2. Use Console.log() Statements
Console.log() statements can be incredibly useful in identifying the location of an error. By strategically placing console.log() statements throughout your code, you can track the state of variables and identify where the code breaks down.
3. Use Breakpoints
Breakpoints allow developers to pause their code at a specific point in time and inspect the state of the program. By using breakpoints, you can identify the exact line of code where an error occurs, and inspect the values of variables and function calls at that point in time.
4. Debug in Small Chunks
When working with complex applications, it can be overwhelming to try to debug the entire codebase at once. Instead, break your code down into smaller, manageable chunks and debug them individually. This can make the debugging process less daunting and more effective.
5. Understand the Error Message
