js实现英文换行并用中划线-连接

css设置 hyphens: auto; 可以实现效果，但是谷歌不支持…
js实现代码如下：

function wrap(str,len){
    return str.replace(new RegExp("(.{"+(len)+"})","igm"),"$1<br/>")
      .replace(/(\w)(<br\/>\w)/igm,'$1<font color=#000>-</font>$2');
}

                                                                           
const text = wrap("Everything has an beginning has an end Everything has an beginning has an end Everything has an beginning has an end Everything has an beginning has an end...",22);
  
  
document.write(text)

效果如下：
