How to format JSON with Angular json pipe
Displaying JSON objects in a readable format is essential for debugging and visualizing complex data structures in Angular applications. As the creator of CoreUI with over 11 years of Angular experience since 2014, I’ve used JSON formatting extensively for development and debugging. The most straightforward solution is to use Angular’s built-in json pipe, which converts objects to formatted JSON strings. This pipe is invaluable for quick debugging and displaying API responses during development.
How to throw an error in JavaScript
Throwing errors is essential for handling invalid states and exceptional situations in JavaScript applications effectively.
As the creator of CoreUI with over 25 years of development experience, I’ve built robust error handling into countless production systems.
The most effective solution is to use the throw statement with an Error object, providing clear error messages.
This approach makes debugging easier and allows proper error handling with try-catch blocks.
How to measure execution time in JavaScript
Measuring execution time is essential for optimizing code and identifying performance bottlenecks in your JavaScript applications.
As the creator of CoreUI with over 25 years of development experience, I’ve measured and optimized thousands of functions across various projects.
The most straightforward and accurate solution is to use console.time() for quick measurements or performance.now() for high-precision timing.
Both methods are built into modern browsers and provide reliable results.
How to profile performance in JavaScript
Understanding performance bottlenecks is crucial for building fast, responsive web applications that provide excellent user experience. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve optimized countless applications and components for maximum performance. The most effective solution for profiling JavaScript performance is to use Chrome DevTools Performance tab combined with the Performance API. These tools provide detailed insights into execution time, rendering, and resource usage.
How to blame a file in Git
Git blame shows line-by-line authorship information for files, helping track down when and who made specific changes for debugging and code review.
As the creator of CoreUI with over 25 years of development experience, I use git blame regularly to understand code history and track down the source of bugs or features.
The most straightforward approach is using git blame filename to see author, commit hash, and timestamp for every line in a file.
This command is invaluable for collaborative development and understanding code evolution over time.
How to handle errors in Express
Proper error handling is crucial for building robust Express applications that gracefully handle failures and provide meaningful responses to clients. As the creator of CoreUI with over 25 years of backend development experience, I’ve implemented error handling systems across numerous production APIs. The most effective approach is using Express’s built-in error handling middleware combined with custom error classes for different error types. This ensures consistent error responses and proper logging while preventing application crashes.
How to use try-catch in JavaScript
Using try-catch blocks in JavaScript enables robust error handling that prevents application crashes and provides graceful failure management. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve implemented comprehensive error handling in countless production applications and component libraries. From my expertise, the most effective approach is wrapping potentially error-prone code in try blocks and handling exceptions in catch blocks with appropriate fallback strategies. This pattern ensures applications remain stable and provide meaningful feedback when unexpected errors occur.
How to set breakpoints in JavaScript
Setting breakpoints allows pausing JavaScript execution at specific lines to inspect variables, examine call stacks, and step through code for effective debugging.
With over 25 years of experience in software development and as the creator of CoreUI, I’ve used breakpoints extensively for troubleshooting complex logic, performance analysis, and understanding code flow.
From my expertise, the most versatile approach is using the debugger statement in code or setting visual breakpoints in browser developer tools.
These methods provide precise control over execution flow and comprehensive debugging capabilities.
How to debug in Chrome DevTools with JavaScript
Using Chrome DevTools for JavaScript debugging provides powerful inspection capabilities, breakpoint management, and real-time code analysis for effective troubleshooting. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve relied on Chrome DevTools extensively for debugging complex applications, performance optimization, and development workflow. From my expertise, the most effective approach is combining console logging, breakpoint debugging, and the Sources panel for comprehensive code inspection. These tools provide complete visibility into code execution, variable states, and runtime behavior.
How to use console.table in JavaScript
Using console.table provides a clean, organized way to view arrays and objects in a tabular format, making data inspection much easier during debugging.
With over 25 years of experience in software development and as the creator of CoreUI, I’ve used console.table extensively for debugging complex data structures and API responses.
From my expertise, the most effective approach is passing arrays of objects to console.table() to create well-organized, readable output in the browser console.
This method transforms complex data into easily scannable tables with columns and rows.
