How do you match group differences in JavaScript?

A regex /^[a-z]*$/

is a fast way to match all characters in a range.

But how can I remove a group of characters from this range?

For example, which regex matches a-z

with e,o,u

excluded?

Of course I can manually place multiple ranges, but I'm wondering if there is a better way?

EDIT. A similar but broader question is not specific to JavaScript. However JavaScript has a special relationship with regular expressions, for example here . Many expressions from other languages ​​don't work in JavaScript, so I feel that some of the more specific JS questions deserve some credit.
