还以为'9' - '0'跟C语言里面语法的一样呢

function string2int(s) { var temp = s.split(''); var arr = temp.map(Number); return temp.reduce(function(x,y){ return x*10+y; }); }

function string2int(s) {
  var temp = s.split('');
  var arr = temp.map(Number);
  return arr.reduce(function(x,y){
    return x*10+y;
  });
}
console.log(string2int('12345'));

除了这样转换成数字 return x.charCodeAt(0) - '0'.charCodeAt(0); 还有其它方法吗？
