RavdecJs - javascript implementation of ravdec

Ravdec is a module written in python, which is based on a Lossless Data Compression Algorithm designed by Ravin Kumar on 19 September, 2016.This compression algorithm have a fixed compression ratio of 1.1429 in all possible cases, It accepts data of following format: alphabets,numbers, and symbols.It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate. In this case also, the above module, and algorithm gives the same compression ratio.

Ravdec- LossLess Data Compression

Algorithm Designer, and Module Developer: Ravin Kumar

This compression algorithm have a fixed compression ratio of 1.1429 in all possible cases, It accepts data of following format: alphabets,numbers, and symbols. Example: It can compress 1 GB to 896 MB.

Application of Ravdec

It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate. In this case also, the above module, and algorithm gives the same compression ratio.

NOTE- The data that is to be compressed should have length of multiple of 8.(i.e 8 elements, or 16 elemnts or 24...so on)

• compression("data to be compressed of length of multiple of 8 ") - To compress the original data to transmit, that is needed to be transmitted.
• decompression(" previously compressed data") - To decompress the previously compressed data, that is received.

It is used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the propability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate.

Example:

const ravdec=require("./ravdec.js");
ravdec_obj=new ravdec();
// for compression
var compressed_data=ravdec_obj.compression("ASDFGHJK");

// note- data to be compressed should have length of multiple of 8.
// (i.e 8 elements, or 16 elemnts or 24...so on) for decompression

var decompressed_data=ravdec_obj.decompression("previously compressed data");

Application of this module:

It can be used where the machine generates data at a very fast rate, that it became difficult for other algorithms to calculate the probability of a symbol, as data keeps on getting large, and is transmitted over the network with a much faster rate. In this case also, the above module, and algorithm gives the same compression ratio.
