Additionally `prefixValue` can accept full declarations to avoid

     

       
43

having to apply it before concatenation, which can be useful in case

you're trying to minimise string operations:

46
       
+
       
```js

     

       
47
       
+
       
const declaration = 'position: sticky';

     

       
48
       
+
       
prefixValue(declaration, declaration); // 'position: -webkit-sticky, sticky'

     

       
49

```
