Yes, but it relies on an ES5 feature of JavaScript. This means it will not work in IE8 or older.

var result = objArray.map(function(a) {return a.foo;});

On ES6 compatible JS interpreters you can use an arrow function for brevity:

var result = objArray.map(a => a.foo);

Array.prototype.map documentation

You can use array.prototype.find:

var names = [{name: 'joe', age: 'nine'}, {name: 'tom', age: 'ten'}];
var someFun = (nm) => {        
    var found = names.find(el => el.name === nm);
    return found && found.age || null; 
}
console.log(someFun('tom'));

You can loop over the array and test for that property:

function search(nameKey, myArray){
    for (let i=0; i < myArray.length; i++) {
        if (myArray[i].name === nameKey) {
            return myArray[i];
        }
    }
}

const array = [
    { name:"string 1", value:"this", other: "that" },
    { name:"string 2", value:"this", other: "that" }
];

const resultObject = search("string 1", array);
console.log(resultObject)

You can iterate through the object keys and save the name in the array using push:

example = [{
  name: "someone1",
  city: "somewhere1",
  state: "someplace1"
}, {
  name: "someone2",
  city: "somewhere2",
  state: "someplace2"
}];
var arrNames = [];
//iterate through object keys
Object.keys(example).forEach(function(key) {
  //get the value of name
  var val = example[key]["name"];
  //push the name string in the array
  arrNames.push(val);
});
console.log(arrNames);//prints ["someone1", "someone2"]

After @Felix suggestion(with which I agree) there is no need to use Object.keys:

example = [{
  name: "someone1",
  city: "somewhere1",
  state: "someplace1"
}, {
  name: "someone2",
  city: "somewhere2",
  state: "someplace2"
}];
var arrNames = [];
//iterate through object keys
example.forEach(function(item) {
  //get the value of name
  var val = item.name
  //push the name string in the array
  arrNames.push(val);
});
console.log(arrNames); //prints ["someone1", "someone2"]

Object.keys()

Array.prototype.forEach()

Array.prototype.push()

Might be when you are executing that line this.props.users is undefined. Check the flow where you have added console.log(this.props.users[0])

You are trying to get the value from the first element of the array. ie, data[0]. This will work:

console.log(data[0].value);

If you have multiple elements in the array, use JavaScript map function or some other function like forEach to iterate through the arrays.

data.map(x => console.log(x.value));

data.forEach(x => console.log(x.value));

For those who want to return object with all properties unique by key

const array =
  [
    { "name": "Joe", "age": 17 },
    { "name": "Bob", "age": 17 },
    { "name": "Carl", "age": 35 }
  ]

const key = 'age';

const arrayUniqueByKey = [...new Map(array.map(item =>
  [item[key], item])).values()];

console.log(arrayUniqueByKey);

   /*OUTPUT
       [
        { "name": "Bob", "age": 17 },
        { "name": "Carl", "age": 35 }
       ]
   */

 // Note: this will pick the last duplicated item in the list.
