如何根据每个 object 中的数组从 object 数组中返回某些对象？

Question

例如，如果我想从下面的数组中获取具有“读取”技能的所有对象的新数组，我该怎么做？

我尝试了 testResult 但只是得到了无限循环:(

感谢所有和任何帮助！

const people = [{
    name: "Jon",
    skills: ["reading", "acting", "drinking"],
},
{
    name: "Tim",
    skills: ["rowing", "hockey", "reading"],
},
{
    name: "Lucy",
    skills: ["business", "learning", "hockey"],
},
{
    name: "Michelle",
    skills: ["running", "business", "sleeping"],
},
{
    name: "Michael",
    skills: ["making friends", "surfing"],
}

]

预期收益：

[{
    name: "Jon",
    skills: ["reading", "acting", "drinking"],
},
{
    name: "Tim",
    skills: ["rowing", "hockey", "reading"],
}]

const testResult = testArray.map((obj) => {
obj.skills.map((skill) => {
    if (skill === "reading") {
        setPeople([...people, obj])
    }
})

})

Answer 1

尝试这个

people.filter((e) => e.skills.indexOf('reading') > -1)

Answer 2

var people_new = []; 

for(var i = 0; i < people.length; i++) 
{

   var skills = people[i].skills; 
   
   for(var s = 0; s < skills.length; s++) 
   {
      if( skills[s] == "reading" ) 
      {
         people_new.push(people[i]); 
      }
   }

}

Answer 3

let filterd = [] for(item of people){ if(item.skills.includes('reading')){ filterd.push(item) } } console.log(filtered) // array of objs
