javascript - 如何通过最接近的范围值查找对象名称？

Question

我的尝试:

var objects = [
  {"min":"0","max":"50","name":"name1"},
  {"min":"50","max":"100","name":"name2"},
  {"min":"100","max":"150","name":"name3"}
];

var value = 40;

objects.forEach(function(item, i){
    if(Number(item.min) >= value &&  value <= Number(item.max) ){
    console.log("name is ", item.name );
  }
});

获取控制台:

name is  name2
name is  name3

但我的期望是名称是name2使用场景获取范围值的正确方法是什么？

使用Array#find方法:

var objects = [
  {"min":"0","max":"50","name":"name1"},
  {"min":"50","max":"100","name":"name2"},
  {"min":"100","max":"150","name":"name3"}
];

var value = 90;

let res = objects.find(obj => Number(obj.min) <= value && value <= Number(obj.max));
console.log(res ? res.name : 'Not found');
