### fromCamelCase
|
|
|
|
Converts a string from camelcase.
|
|
|
|
Use `replace()` to remove underscores, hyphens and spaces and convert words to camelcase.
|
|
Omit the second argument to use a default separator of `_`.
|
|
|
|
```js
|
|
const fromCamelCase = (str, separator = '_') =>
|
|
str.replace(/([a-z\d])([A-Z])/g, '$1' + separator + '$2')
|
|
.replace(/([A-Z]+)([A-Z][a-z\d]+)/g, '$1' + separator + '$2').toLowerCase();
|
|
// fromCamelCase('someDatabaseFieldName', ' ') -> 'some database field name'
|
|
// fromCamelCase('someLabelThatNeedsToBeCamelized', '-') -> 'some-label-that-needs-to-be-camelized'
|
|
// fromCamelCase('someJavascriptProperty', '_') -> 'some_javascript_property'
|
|
```
