infinite-sequence-generator

Infinite Key Generator

Creates a sequence of strings that can be compared by > and < operators (and therefore sort). The sequence never ends (doesn't overflow like a number at 2^52) and the memory footprint scales logarithimcally.

How it works

Well it returns a generator that's yields a sequence of keys of all printable ASCII 7-bit character set and uses that set as digits.

Install dependency from npm

npm install infinite-sequence-generator

Then use it in the code as you like it:

const fini = require("infinite-sequence-generator");

const seq = fini();
seq.next().value;   // __!

// or maybe as an iterator

let i = 0;
for (var key of seq) {
    console.log(key);
    if (i++ > 10) break;
}

You may add a sequence prefix if you like.

const seq = fini("AAA__");

console.log(seq.next().value); // AAA__!
