lodash find 只返回一个结果

Question

I'm using lodash find, and on my test, it is only returning one result, is this the expected response? how to find all instances?

var users = [
    { firstName: "John", lastName: "Doe", age: 28, gender: "male" },
    { firstName: "Jane", lastName: "Doe", age: 5, gender: "female" },
    { firstName: "Jim", lastName: "Carrey", age: 54, gender: "male" },
    { firstName: "Kate", lastName: "Winslet", age: 40, gender: "female" }
  ];

  var encontre = _.find(users, { lastName: "Doe" })

  console.log("usuario encontre::", encontre)

response

usuario encontre:: { firstName: 'John', lastName: 'Doe', age: 28, gender: 'male' }

so how to seethe 2 users with lastName: Doe?

thanks

Try with _.filter as _.find returns the first matched element. _.filter will return an array of all matched elements.

var users = [
    { firstName: "John", lastName: "Doe", age: 28, gender: "male" },
    { firstName: "Jane", lastName: "Doe", age: 5, gender: "female" },
    { firstName: "Jim", lastName: "Carrey", age: 54, gender: "male" },
    { firstName: "Kate", lastName: "Winslet", age: 40, gender: "female" }
  ];

  var encontre = _.filter(users, { lastName: "Doe" })

  console.log("usuario encontre::", encontre)
