How do I go about removing all digits and all punctuations in a string?

Question

How do I go about removing all digits and all punctuations in a string using regex?
For example: From Eric-Has555-Books to EricHasBooks

I am trying to use String.replace(), but my regex below doesn't work:

str = 'Eric-Has555-Books'
reg = /[0-9]-/g;
str.replace(reg, '');

You were close, the `-` should be inside the `[]`: `/[0-9\-]/g`. There's no need to escape it, but I prefer to do it for readability purpose. — Karl-André Gagnon, Sep 06 '19 at 15:51

You can use [^a-z] which says "Remove everything that isn't a letter". This is also known as Negated Character Classes

let r = 'Eric-Has555-Books'.replace(/[^a-z]/gi, '')

console.log(r)

That question is nine years old and SO standards were different back then. Although I just downvoted it and flagged it as too broad. Thanks. – j08691 Sep 06 '19 at 15:50
