I have tried variations of two similar questions here:

[Sort mixed alpha/numeric array](https://stackoverflow.com/questions/4340227/sort-mixed-alpha-numeric-array?fbclid=IwAR0BA7Gg-dXox5e7HfHp5cxxOUEo4y5Kx665_5gVthG1s2CkXqZhItv7uGA)

and here:

[Sort mixed alpha/numeric Array in javascript](https://stackoverflow.com/questions/57625059/sort-mixed-alpha-numeric-array-in-javascript?fbclid=IwAR3chqJuW9DD9tTNiy_afbfOlyvdD01imSL1MXrKJxbb6UQfTnhk5wafdEc)

But can't get the sort algorithm correct.

For example this solution:

```
const sortAlphaNum = (a, b) => a.localeCompare(b, 'en', { numeric: true })`

```

Gives it in the format of `["A1", "A2", "A3"...]` whereas I want it in the format of `["A1", "B1", "C1"...]`.

The array ranges from `A1` to `M30` if that helps so only one letter but two numbers.
