Javascript regular expressions to remove character from a strings

Question

I would like to remove all occurrences of the words "hello" and "-hello" in a string, the "-" in "-hello" is a minus sign.

I am currently doing it as such

let regex = /hello/-hello/g

let word = "Hello, How are -hello you doing"

let newWord = word.replace(regex,'')

But this seems to throw an error, what is that correct way to do this?

thank you

The error is thrown because you're using / instead of |. The / after hello closes the regex literal. — adiga

Try this,

    let regex =  /-?hello/gi;
    
    let word = "Hello, How are -hello you doing"
    
    let newWord = word.replace(regex,'')
    
    console.log(newWord);
