Function snakeCase

snakeCase(value: string): string
Convert a string to snake_case. Words are lowercased and joined with single underscores. A word boundary is any of: a run of non-alphanumeric characters (dropped), a lower-or-digit followed by an uppercase letter (fooBar), or the tail of an acronym (XMLHttp → xml_http). Word detection and casing are both Unicode-correct, not ASCII-only.

This is the inverse of camelCase and additionally splits camelHumps, which is the usual reason to reach for it: snakeCase('fooBar') is 'foo_bar'.
Parameters
- value: string
  The string to convert.
Returns string
The snake_case string. An empty string is returned unchanged.
Example
```
snakeCase('hello world') // => 'hello_world'
snakeCase('fooBar') // => 'foo_bar'
snakeCase('XMLHttpRequest') // => 'xml_http_request'
snakeCase('baz-qux') // => 'baz_qux'
snakeCase('héllo wörld') // => 'héllo_wörld'
```
