Remove multiple punctuations followed by punctuations javascript

Question

Am trying to remove the ,|- symbols I have tried the following.

var s="very good ,. hello |. how -. are. you|";
s = s.replace(/,+(?=\.)/g, "");

console.log(s)

Am not able to remove any punctuations which are followed by fullstop or followed by multiple symbols.Can any one help me out expected result

 very good . hello . how . are. you|

Try s = s.replace(/([.,|-])+/g, "$1"). However, your requirements are still not clear to me. — Wiktor Stribiżew

"any punctuations which are followed by fullstop" is clear, but what do you mean by "followed by multiple symbols"? — John Hascall

If you want to remove all punctuation that are preceded by punctuation, use this. I am unsure what you are expecting. I have included two solutions, one to keep only the last symbol, and one to keep only the first...

var s="very good ,. hello |. how -. are. you|";
console.log("First try: "  + s.replace(/([,|.-])[\s]*[,|.-]+/g, "$1"));
console.log("Second try: " + s.replace(/[,|.-]+[\s]*([,|.-])/g, "$1"));

You're very close, add the other punctuations in a character class:

var s="very good ,. hello |. how -. are. you|";
s = s.replace(/[,.|-]+(?=\.)/g, "");

console.log(s)

@shansetivikas: You aren't very clear, my regex remove the punctuations that are before a dot, as specified in question. If it isn't what you want, please edit yoyr question and add test cases and expected result for each.

@shansetivikas: Is it OK? It gives very good . hello . how . are. you| as wanted, isn't it?
