How to check if array of object contains a string

rated 0 times [ 43] [ 1] / answers: 1 / hits: 19846 / 5 Years ago, tue, may 14, 2019, 12:00:00

let's say I have an array of objects:

let arr = [

   {

    name: 'Jack',

    id: 1

   },

   {

    name: 'Gabriel',

    id: 2

   },

   {

    name: 'John',

    id: 3

   }

]

I need to check whether that array includes the name 'Jack' for example using:

if (arr.includes('Jack')) {

   // don't add name to arr



} else {

  // push name into the arr



}

but arr.includes('Jack') returns false, how can I check if an array of objects includes the name?

Since you need to check the object property value in the array, you can try with Array.prototype.some():

The some() method tests whether at least one element in the array passes the test implemented by the provided function. It returns a Boolean value.

let arr = [

   {

    name: 'Jack',

    id: 1

   },

   {

    name: 'Gabriel',

    id: 2

   },

   {

    name: 'John',

    id: 3

   }

]

var r = arr.some(i => i.name.includes('Jack'));

console.log(r);
