\nNow, I realize that I\u2019m letting my inner geek show here, but I really think this is wildly cool. \u00a0You can now run functional<\/em> logic within the scope of a procedural<\/em> object. \u00a0It really doesn\u2019t get much cooler than that!
\nAll that said, there are some serious caveats you need to consider:<\/p>\n
\nIf you start your own thread, you\u2019re responsible for stopping it. \u00a0Make sure you factor this responsibility into your code.<\/li>\n
The numbers of threads allowed in the JVM is finite. \u00a0You want to start (and stop) your threads explicitly, gracefully, and use them sparingly. \u00a0Keep in mind that a custom process spinning up a large number of threads could potentially conflict with other processes in the pipeline.<\/li>\n
Don\u2019t use a thread in your pipeline unless it is absolutely necessary.<\/li>\n<\/ol>\n\u00a0
\nSo to summarize: Threading is now possible in JavaScript, and it\u2019s pretty darn cool, but use it wisely.<\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
