A tiny (491 bytes) JavaScript timer library built on the User Timing API's performance.mark() and performance.measure(), with fallbacks to performance.now(), Date.now(), or process.hrtime() in Node. It provides high-resolution timings and produces PerformanceEntries that show up as visualizations in browser DevTools and performance tools.

Use cases

• measure how long a javascript function takes to run
• add high-resolution timing to browser code
• visualize custom performance measurements in chrome devtools
• replace console.time with a more accurate timer
• collect performance entries to send to analytics
• benchmark code in node with high-resolution time

When to choose

• you need accurate, high-resolution timing in the browser or node
• you want measurements to appear in the browser performance timeline and devtools
• bundle size matters and you want a sub-1KB timer

When to avoid

• you need full profiling, tracing, or APM rather than simple timers
• you need benchmarking with statistical analysis of repeated runs
• your environment lacks the User Timing API and you don't want fallback-level accuracy
