| 9 | * Coerces a value to an array of trimmed non-empty strings.
|
|---|
| 10 | * Any input that is not an array, `null` or `undefined` will be turned into a string
|

| 11 | * via `toString()` and subsequently split with the given separator.
|
|---|
| 12 | * `null` and `undefined` will result in an empty array.
|
|---|
| 13 | * This results in the following outcomes:
|
|---|
| 14 | * - `null` -> `[]`
|
|---|
| 15 | * - `[null]` -> `["null"]`
|
|---|
| 16 | * - `["a", "b ", " "]` -> `["a", "b"]`
|
|---|
| 17 | * - `[1, [2, 3]]` -> `["1", "2,3"]`
|
|---|
| 18 | * - `[{ a: 0 }]` -> `["[object Object]"]`
|
|---|
| 19 | * - `{ a: 0 }` -> `["[object", "Object]"]`
|

| 20 | *
|

| 21 | * Useful for defining CSS classes or table columns.
