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

• anubhava: Try regex = /-?\bhello\b/g
• Spirit: Or regex = /(-?hello)/gi
• adiga: The error is thrown because you're using / instead of |. The / after hello closes the regex literal.

Answer 1

Try this,

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

• Toto: This will remove hello in chello or hellois
