Super buggy and doesn't work for most fairly normal code. Don't actually use this :)
./call-trace.js input.js --time > output.js
When the output is loaded and then run, a global variable
_$wɔk is created containing a trace through the code you just ran.
A CPU profile can be generated from the trace:
Then save your clipboard contents and load in Chrome DevTools.
Exploring the data
The global variable
_$wɔk also has the following properties:
file: the full path of the original source file.
fns: a list of all functions found in the file.
t: a record of the call graph. Positive values represent entering a function (with the value indicating a function in
f) and negative values represent exiting a function (with the absolute value indexing
d: a record of timestamps for every entry in
t. Only created if the
--timeoption was specified.
