Javascript/REGEX:删除一个特定的文本(单词),该单词以String中的特定字母开头,单词用空格分隔

Question

我知道这可以通过Regex快速完成:

我得到的字符串如下:

"Alpha OmegaS Sheol Gehena GSSaga Serekali"

我想删除以s开头的单词.

所以我应该:

"Alpha OmegaS Gehena GSSaga"

我试过了什么？

就像是: str.replace(/^\\S/,"") //This NO GOOD.

事情是我非常了解REGEX,但不知何故REGEX不理解我.

任何帮助表示赞赏.

str.replace(/\bs\S+/ig,"")
