(You've definitely used it, just -possibly not known it had a name.)</p> -<p><a href="https://twitter.com/aeleitch">Alex L</a>: I have not!</p> -<p><a href="https://twitter.com/derspiny">Owen J</a>: It's the point where the -execution of the outside system -- the OS, the browser, the Node -runtime, whatever -- stops and the execution of your code starts. Some -platforms only give you one: C on Unix is classic, where there's only -two entry points: main and signal handlers (and a lot of apps only use -main). JS gives you <em>a shit fucking ton</em> of entry points.</p> -<p><a href="https://twitter.com/derspiny">Owen J</a>: In a browser, the pageload -process is an entry point: your code gets run when the browser -encounters a <code><script></code> tag. So is every event handler. There's none -of your code running when an event handler starts, only the browser -is running. So is every callback from an external service, like -<code>XmlHttpRequest</code> or <code>EventSource</code> or the <code>File</code> APIs. In Node, the top -level of your main script is an entry point, but so is every callback -from an external service.</p> -<p><a href="https://twitter.com/aeleitch">Alex L</a>: Ahahahahahahaha oh my -god. There is no way for me to contain them all. <em>everything the light -touches.</em></p> -<p><a href="https://twitter.com/derspiny">Owen J</a>: This is important for -reasoning about exception handling! <em>In JS</em>, exception handling only -propagates one direction: towards the entry point of this sequence of -function calls.</p> -<p><a href="https://twitter.com/aeleitch">Alex L</a>: Yes. This is what <em>I</em> call a -stack trace.</p> -<p><a href="https://twitter.com/derspiny">Owen J</a>: If an exception escapes from -an entry point, the JS runtime logs it, and then the outside runtime -takes over again. That's one of the ways callbacks from external -services fuck up the idea of a stack trace as a map of control flow.</p> -<p><a href="https://twitter.com/aeleitch">Alex L</a>: Huh. Yes. Yes I can see -that. I mean, in my world, control flow is a somewhat handwavey idea -right now. I'm starting to understand why so many people hate JS-land.</p> -<p><a href="https://twitter.com/derspiny">Owen J</a>: Sure. But, for example, a -promise chain is a tool for restructuring control flow. In principle, -error handling should provide <em>some</em> kind of map of that, to allow -programmers -- you -- to diagnose how a program reached a given error -state and maybe one day fix the problem. In THIS future, none of them -do that well, though.</p> -<p><a href="https://twitter.com/aeleitch">Alex L</a>: Yes. Truly the darkest -timeline, but this reviews why I am having these concerns.</p> -</blockquote> - </div> - - - -<div id="comments"> -<div id="disqus_thread"></div> -<script type="text/javascript"> - /* * * CONFIGURATION VARIABLES: EDIT BEFORE PASTING INTO YOUR WEBPAGE * * */ - var disqus_shortname = 'grimoire'; // required: replace example with your forum shortname - - /* * * DON'T EDIT BELOW THIS LINE * * */ - (function() { - var dsq = document.createElement('script'); dsq.type = 'text/javascript'; dsq.async = true; - dsq.src = 'http://' + disqus_shortname + '.disqus.com/embed.js'; - (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(dsq); - })(); -</script> -<noscript>Please enable JavaScript to view the <a href="http://disqus.com/?ref_noscript">comments powered by Disqus.</a></noscript> -<a href="http://disqus.com" class="dsq-brlink">comments powered by <span class="logo-disqus">Disqus</span></a> -</div> - - - - <div id="footer"> - <p> - - The Codex — - - Powered by <a href="http://markdoc.org/">Markdoc</a>. - -<a href="https://bitbucket.org/ojacobson/grimoire.ca/src/master/wiki/dev/entry-points.md">See this page on Bitbucket</a> (<a href="https://bitbucket.org/ojacobson/grimoire.ca/history-node/master/wiki/dev/entry-points.md">history</a>). - - </p> - </div> - -</div> -</body> -</html>
