We have a regexp /Java[^script]/.

Does it match anything in the string Java? In the string JavaScript?

Answers: no, yes.

In the script Java it doesn???t match anything, because [^script] means ???any character except given ones???. So the regexp looks for "Java" followed by one such symbol, but there???s a string end, no symbols after it.
```
alert( "Java".match(/Java[^script]/) ); // null
```
Yes, because the [^script] part matches the character "S". It???s not one of script. As the regexp is case-sensitive (no i flag), it treats "S" as a different character from "s".
```
alert( "JavaScript".match(/Java[^script]/) ); // "JavaS"
```
