### JavaScript
|
||||
## Node.js (and WebPack)
|
||||
|
||||
```bash
|
||||
var hexdump = require('@root/hexdump').hexdump;
|
||||
var hexdump = require('hexdump.js').hexdump;
|
||||
|
||||
var str = hexdump(new Uint8Array([ 0, 1, 2, 127, 254, 255 ]));
|
||||
|
||||
console.log(str);
|
||||
```
|
||||
|
||||
### Browser
|
||||
## Vanilla JS (Browser)
