Javascript GUID generator
npm install dyna-guidA simple guid generator based on timestamp!
The chance to get the same guid is one in 18,446,744,073,709,600,000 on the same millisecond in the same timezone!

`
The difference is that dyna guid is
- hard to generate the same on the same millisecond per timezone _and_
- impossible to generate the same on next millisecond!
`
The default of the random blocks is 2, would be 1 or any other number.
`
import {guid} from "dyna-guid";
console.log('guid', guid());
console.log('even stronger guid', guid(3));
`
function guid(randomBlocks: number = 2): string
Block is a set of 8 chars separated with dashes.
If you need even more complex guids (!why?) you can increase the number of blocks. Or for shorter set it to 1.
Short GUID is a one block guid without hyphen. Useful for short unique ids, easy to copy-paste them.

- Better random blocks
- short guid
