Comparing version 3.1.1 to 3.1.2

lib/readable-stream-browser.js

+/*
+ * This file is used by module bundlers (browserify/webpack/etc) when
+ * including a stream implementation. We use "readable-stream" to get a
+ * consistent behavior between nodejs versions but bundlers often have a shim
+ * for "stream". Using this shim greatly improve the compatibility and greatly
+ * reduce the final size of the bundle (only one stream implementation, not
+ * two).
