Java[^script]

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 part [^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"
```
