例如：var list = [['热', '冷', '冰'], ['大', '中', '小'], ['重辣', '微辣'], ['重麻', '微麻']];
效果如下：

var list = [['热', '冷', '冰'], ['大', '中', '小'], ['重辣', '微辣'], ['重麻', '微麻']];
function compose(list){
var res = list.reduce( (result, property) => {
return property.reduce( (acc, value) => {
return acc.concat(result.map( ele => [].concat(ele, value)));
}, []);
});
return res.map(arr=>arr.join('+'))
}
compose(list);
