Most developers use console.log for debugging, missing DevTools capabilities that accelerate problem-solving. Breakpoints, network throttling, performance profiling, and memory analysis provide deeper insights than log statements alone.
Debugging Techniques
Conditional breakpoints pause execution only when conditions are met. Logpoints add logging without code changes. DOM breakpoints trigger on element modifications. Event listener breakpoints pause on specific events. These capabilities enable targeted debugging without console.log clutter.
- Use conditional breakpoints to pause only on specific cases
- Logpoints provide logging without modifying source code
- Network throttling simulates slow connections for performance testing
- Performance profiler identifies JavaScript bottlenecks
- Memory profiler detects leaks through heap snapshots comparison
Network and Performance
Network panel reveals request waterfalls showing loading sequences. Throttling simulates various connection speeds. Performance timeline visualizes main thread activity. Coverage tool identifies unused CSS and JavaScript. These tools guide optimization efforts effectively.
