Is there a recommended way to convert the output into a string?

[papb]

I've noticed that this module returns an array of numbers. Is there a recommended way to convert the output into a string?

I could use .join(',') for example, but I feel that such approach is contrary to the idea of compression. Surely a lot more information could fit in a string if I use all printable ASCII characters instead of only numbers and a comma.

Thanks!!

Hello, why did you think this is a duplicate of my other question? Maybe if I add some code it will make it more clear:

const lzwcompress = require('lzwcompress');

const data = [{
	foo: ['bar', { baz: 123 }],
	foobar: {
		abc123: true
	}
}];

const compressed = lzwcompress.pack(data);
console.log(compressed);

Output:

[
  123,  34,  95,  95, 107,  34,  58,  91,  34, 102, 111,
  111,  34,  44,  34,  98,  97, 122, 268, 264, 266, 271,
  114, 274,  97,  98,  99,  49,  50,  51,  34,  93, 269,
  258, 118, 261,  91, 256,  48, 291, 270,  97, 278,  44,
  256,  49, 261, 283,  51, 125, 287,  34,  50, 261, 256,
  285,  58, 116, 114, 117, 101, 125, 305, 125
]

The question: is there a recommended way to convert this array of numbers into a string in the context of LZW? I could do compressed.join(',') of course but I think it is likely for another recommended way to exist. (Of course, I would also need a way to un-convert later as a pre-unpack step)
