This is a JavaScript profiler implemented in Node.js, inspired by sjsp, which is implemented in Haskell.
npm -g install node-sjsp
If you want to inject profiling code into something.js, run
sjsp something.js
and then sjsp generates something.sjsp.js in the same directory.
(you can use wildcard characters such that sjsp *.js)
Next, rewrite your HTML code using something.js like below.
<!-- <script src="something.js"></script> -->
<script src="something.sjsp.js"></script>Open the page with your browser and you can see profiles in the JavaScript console every 10 seconds. (you can change this interval by -i option)
