hash-it - npm Package Compare versions

Comparing version 1.3.1 to 2.0.0

CHANGELOG.md

 # hashIt CHANGELOG
 
+#### 2.0.0
+* Use JSON.stringify with replacer as default, without try/catch
+* Move use of try/catch with fallback to prune to new `hashIt.withRecursion` method (only necessary for deeply-recursive objects like `window`)
+* Reorder switch statement for commonality of use cases
+* Leverage typeof in switch statements when possible for performance
+
+#### 1.3.1
+* Add optimize-js plugin for performance in script version
+
 #### 1.3.0
