Javascript / REGEX：删除以字符串中以空格分隔的特定字母（单词）开头的特定文本（单词）

Question

I know this can quickly be done with Regex:

I got string like:

"Alpha OmegaS Sheol Gehena GSSaga Serekali"

I wanna remove words that Starts with s.

So I should have:

"Alpha OmegaS Gehena GSSaga"

What have I tried?

Something like: str.replace(/^\\\\S/,"") //This NO GOOD.

The thing is I understand REGEX very well, but somehow REGEX does NOT understand me.

Any help is appreciated.

How about:

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