Structural JavaScript Profiler

Structural JavaScript Profiler

See about structural and sampling JavaScript profiling.

trace is a JavaScript library for measuring code execution time.
It provides a simple way to benchmark code, allowing measurement of the performance of individual functions and nested calls.

Wrap the code to benchmark with the on(label) and off(label) functions.

trace.on("my function 1")
// your code
trace.off("my function 1")

Benchmarking can be structured as a nested hierarchy of on/off calls.

trace.on("my function 1")
    trace.on("inner function", { skip: 10, take: 100 })
    // your code
    trace.off("inner function")
trace.off("my function 1")

To generate an execution report, call the trace.report() method from the code or dev tools console.
This will open a popup window with an expandable table representing the call hierarchy and benchmarks.
