Javascript Regex Replace Multiple Patterns

Question

I'm trying to do a replace for every pattern that looks like either:

" - ", // space dash space
" ", // space
"*", // asterisk

and replace it with a space.

I tried:

const name = "Test - number one*"
const regExName = name.replace((\s-\s)|(-)|(\s)|(\*)/g, '_');

Obviously wrong... Help please?

Simply use this pattern:

/ - | |\*/g

And here is full code:

const name = "Test - number one*"
const regExName = name.replace(/ - | |\*/g, '_');
document.write(regExName);

Answer 2

You are missing the leading /:

name.replace(/(\s-\s)|(-)|(\s)|(\*)/g, '_');
