Regular Expression starts with @ symbol

Question

In regular expression, how do I look for matches that start with an @symbol? The symbol cannot be in the middle of a word (link in an email address).

For example, a string that looks like this:

@someone's email is [email protected] and @someoneelse wants to send an email.

The expression I'd use is /^@[\w]/g

It should return:

@someone's

@someoneelse

The expression I use doesn't seem to work.

Answer 1

You can utilize \B which is a non-word boundary and is the negated version of \b.

var s = "@someone's email is [email protected] and @someoneelse wants to send an email.",
    r = s.match(/\B@\S+/g);

console.log(r); //=> [ '@someone\'s', '@someoneelse' ]
