 # HdrHistogramJS
 
 TypeScript port of HdrHistogram for NodeJS and web browsers.  
-Since version 2, HdrHistogramJS comes in 2 flavors: the good old TypeScript implementation and a brand new WebAssembly implementation. This new WebAssembly implementation leverages on AssemblyScript to bring a significant performance boost. Since some caution must be taken using this WebAssembly implementation it is not enabled by default. Check out the [WebAssembly section](#boosting-performances-with-webassembly-since-hdrhistogramjs-v2) for more details on this topic.

 Since version 2, HdrHistogramJS leverages on WebAssembly to speed up computations. Depending on the use case, the performance boost can be as high as twice as fast :)

 To benefit from WebAssembly performance boost, there are three things to take care of:
