Find a value in an array of objects in Javascript [duplicate]

Question

I know similar questions have been asked before, but this one is a little different. I have an array of unnamed objects, which contain an array of named objects, and I need to get the object where "name" is "string 1". Here is an example array.

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

Update: I should have said this earlier, but once I find it, I want to replace it with an edited object.

Answer 1

Finding the array element:

let arr = [      { name:"string 1", value:"this", other: "that" },      { name:"string 2", value:"this", other: "that" }  ];    let obj = arr.find(o => o.name === 'string 1');    console.log(obj);

Replacing the array element:

let arr = [      { name:"string 1", value:"this", other: "that" },      { name:"string 2", value:"this", other: "that" }  ];    let obj = arr.find((o, i) => {      if (o.name === 'string 1') {          arr[i] = { name: 'new string', value: 'this', other: 'that' };          return true; // stop searching      }  });    console.log(arr);

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

function search(nameKey, myArray){     for (var i=0; i < myArray.length; i++) {         if (myArray[i].name === nameKey) {             return myArray[i];         }     } }  var array = [     { name:"string 1", value:"this", other: "that" },     { name:"string 2", value:"this", other: "that" } ];  var resultObject = search("string 1", array);
