 ### **Conclusion**
 
+#### Popular != Performant

+- It's quite funny to notice the two most popular nodejs libs `languagedetect` (really high in google) and `franc` (over 4k stars on github) are both at the bottom of the charts.
+- At the opposite `langdetect` which is quite unknown performs really well and is the only one to come close to `tinyld`.

 #### Recommended
 
 - For **NodeJS**: `TinyLD`, `langdetect` or `node-cld` (fast and accurate)
