Js jquery version of the thousands of bit Conversion Function (non-regular, extremely efficient)

I didn't expect js to have no processing functions formatted in thousands of BITs (for example, 1,234.01). I searched the internet and processed them in regular expressions. The efficiency of regular expressions is not flattering, and the resource consumption speed is slow (although the processing will be more intuitive ).

Therefore, a pure numeric processing function is specially written to process the final output string with thousands of sub-bits and encapsulated into a jQuery function package. The processing efficiency is very high and can be used frequently and directly on the code. You can also click to download the min compression version.

If you are not using the jQuery environment, you can use the source code and re-encapsulate it into your own functions.
