Javascript: How to use a regular expression in a loop

Question

I have a question. I want to build a regular expression in java script within a loop. I have the string "hi!whats.up" and I want to select in the loop each substring ("hi!","whats","up"), with a regular expression.

Thank you in advance.

@Tester thx for your answer. I have no code yet and don't want have the whole code from anybody. I just want to understand the regular expression of this example. I know that I can use " [.].* " But this just takes the substring ".up". And I want to have all three pieces in the regex. — Cevi Tas

Do you want to include the ! with the preceding word but not other special characters? — JollyJoker

You want to use .split() together with a regular expression for symbols.

Something like

"hi!whats.up".split(/[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/)
    .forEach(function (word) {
        console.log(word);
})

thank you. So is "word" my variable? Like var String word="hi!whats.up" ?

when I compile that I get an error at the (/[-!$%^&*()_+|~=`{}[]:";'<>?,.\/]/)

No, that's just for logging. The hardcoded "hi!whats.up" is what's being split

let [a, b, c] = 'hi!whats.up'.split (/[^\w]+/)
