+Converts a string to snakecase.
+
+Use `replace()` to add underscores before capital letters, convert `toLowerCase()`, then `replace()` hyphens and spaces with underscores.
+
+```js
+const toSnakeCase = str =>
+  str.replace(/(\w)([A-Z])/g, '$1_$2').replace(/[\s-_]+/g, '_').toLowerCase();
+// toSnakeCase("camelCase") -> 'camel_case'
+// toSnakeCase("some text") -> 'some_text'
+// toSnakeCase("some-javascript-property") -> 'some_javascript_property'
+// toSnakeCase("some-mixed_string With spaces_underscores-and-hyphens") -> 'some_mixed_string_with_spaces_underscores_and_hyphens'
