如何从Javascript中的字符串中删除以某个字符开头的单词

Question

I have a string like

'here is some #tweet from @someone to @somebody-else'

and I need to remove all the words (and-phrases) that start with @mentions and return the string without them, so that it becomes

'here is some #tweet from to'

How to do that in Javascript?

Thank you!

Answer 1

var str = 'here is some #tweet from @someone to @somebody-else';

str = str.replace(/\s?@\S+/g, '');

Answer 2

var s = 'here is some #tweet from @someone to @somebody-else';
s = s.replace(/\s?@[\w-]+/g, "");
//here is some #tweet from to
