JS实现的驼峰式和连字符式转换功能分析

var s = "fooStyleCss";
s = s.replace(/([A-Z])/g,"-$1").toLowerCase();
//利用正则进行替换,简洁明了,很棒

var s1 = "foo-style-css";
s1 = s1.replace(//-(/w)/g, function(all, letter){
 return letter.toUpperCase();
});

var s = "style-sheet-base";
var a = s.split("-");
var o = a[0];
for(var i=1;i<a.length;i++){
  o = o + a[i].slice(0,1).toUpperCase() + a[i].slice(1);
}

var s1 = "style-sheet-base";
s1 = s1.replace(//-(/w)/g, function(x){return x.slice(1).toUpperCase();});
