/**

|
|
Convert a string to a valid [JavaScript identifier](https://developer.mozilla.org/docs/Glossary/Identifier).
|
||
|
|
|
||
|
|
Different inputs will always generate unique identifiers.
|
||
|
|
|
||
|
|
@example
|
||
|
|
```
|
||
|
|
import toValidIdentifier from 'to-valid-identifier';
|
||
|
|
|
||
|
|
toValidIdentifier('foo');
|
||
|
|
//=> 'foo'
|
||
|
|
|
||
|
|
toValidIdentifier('foo-bar');
|
||
|
|
//=> 'foo$j$bar'
|
||
|
|
|
||
|
|
toValidIdentifier('$');
|
||
|
|
//=> '$a$'
|
||
|
|
|
||
|
|
toValidIdentifier('undefined');
|
||
|
|
//=> '$_undefined$'
|
||
|
|
```
|
