TS throws an error:

```
'parsedHours' is never reassigned. Use 'const' instead    prefer-const
'parsedMinutes' is never reassigned. Use 'const' instead  prefer-const

```

When trying to deconstruct this array, after a string split:

```
let [
  parsedHours = '00',
  parsedMinutes = '00',
  parsedSeconds = '00',
  parsedMillis = '000'
] = "12:34:56".split(':');

if (parsedSeconds.includes('.')) {
  [parsedSeconds, parsedMillis] = parsedSeconds.split('.');
}

```

**Hours** and **minutes** should be declared as constants, but **Seconds** and **Millis** may change, thus should be declared as let.
This can be fixed in many approaches, but I can't find a beautiful way of doing this.

Any ideas?
