遍历
some() 方法用于检测数组中的元素是否满足指定条件（函数提供）只返回true/false

var arr = ["admin", "editor"]
var obj= {
  roles: ["admin", "editor", "operator"]
}
arr.some(item=> obj.roles.includes(item))

var ages = [4, 12, 16, 20];
var aaaa = ages.some(function(age) {
    return age >= 30;
});
console.log(aaaa)
//false

注意：有返回值，true/false
