Javascript compression algorithm which compresses into strings?

Question

Hello I am a high school student who is new to coding and I am working on a science fair project. For my project I am required to use a compression algorithm, due to my lack of knowledge I am restricted to javascript. I found a compression algorithm in jslzjb but the algorithm compresses the message into a byte array when I need it in strings.

Is there a way to compress a message into strings using javascript, by the way I need the compression algorithm to be lossless.

Thanks

Perhaps you can just convert your byte array into a string of some sort? — Jasper

A simple way to handle your problem is to encode binary data using Base64, although this introduces an overhead of 33%. — NullUserException

I actually tried that, what would happen is I would use the toString function however all this would cause is an expansion of the array actually causing the message to actually get bigger in size. I also tried using base64 given by jslzjb it also resulted in the message increasing in size slightly. — user1767004

That's just the nature of the beast. Why are you restricted to JS again? — NullUserException

I am new to coding, all I have learned is javascript. What I am looking for is a way of compressing into strings. Can I not do that in Javascript? Would I need to use a different language? — user1767004

The following compression algorithm is written by Curto in Javascript, and works directly on streams : https://github.com/pierrec/node-lz4
