I want to remove all special characters from string and add only one "-"(hyphen) in the place.

Consider below example

var string = 'Lorem%^$&*&^Ipsum#^is@!^&simply!dummy text.'

So, from the above string, if there is a continuous number of special characters then I want to remove all of them and add only one "-" or if there is a single or double special character then also that should be replaced by "-"

Result should be like this

Lorem-Ipsum-is-simply-dummy text-

I have tried below, but no luck

var newString = sourceString.replace(/[\. ,:-]+/g, "-");

You could use .replace to replace all non-alphabetical character substrings with -:

const input = 'Lorem%^$&*&^Ipsum#^is@!^&simply!dummy text.';
const output = input.replace(/[^\w\s]+/gi, '-');
console.log(output);

If you want to permit numbers too:

const input = 'Lorem123%^$&*&^654Ipsum#^is@!^&simply!dummy text.';
const output = input.replace(/[^\w\s\d]+/gi, '-');
console.log(output);

@AmolRokade It's already removed from the string..? I want to remove all special characters from string and add only one "-" in the place.
@AmolRokade Your desired output includes the space. I highly recommend trying to figure out what you want the output to be like before posting a question.
