This method should be used before you use any of the methods which would otherwise alter the global `Bluebird` object - to avoid polluting global state. A basic example: ```js var Promise = require('bluebird'); var Promise2 = Promise.getNewLibraryCopy(); Promise2.x = 123; console.log(Promise2 == Promise); // false console.log(Promise2.x); // 123 console.log(Promise.x); // undefined ``` `Promise2` is independent to `Promise`. Any changes to `Promise2` do not affect the copy of Bluebird returned by `require('bluebird')`. In practice: ```js var Promise = require('bluebird').getNewLibraryCopy(); Promise.coroutine.addYieldHandler( function() { /* */ } ); // alters behavior of `Promise.coroutine()` // somewhere in another file or module in same app var Promise = require('bluebird'); Promise.coroutine(function*() { // this code is unaffected by the yieldHandler defined above // because it was defined on an independent copy of Bluebird }); ``` </markdown></div> <div id="disqus_thread"></div> <script type="text/javascript"> var disqus_title = "Promise.getNewLibraryCopy"; var disqus_shortname = "bluebirdjs"; var disqus_identifier = "disqus-id-promise.getnewlibrarycopy"; (function() { var dsq = document.createElement("script"); dsq.type = "text/javascript"; dsq.async = true; dsq.src = "//" + 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="https://disqus.com/?ref_noscript" rel="nofollow">comments powered by Disqus.</a></noscript>
