How to get a specific JSON element from an array of objects (jQuery)

Question

I'm using the following JavaScript/jQuery commands to display JSON array data on a HTML page:

$(document).ready(function() {
  $.getJSON("article.json", function(data){
    console.log(data) //just to log in console as well
    var article_data = '';
    $.each(data, function(key, value){
      article_data += '<div class="page-title">' + value.title + '</div>';
    });
    $('#container').append(article_data);
  });
});

But I want to only display the array for id4 of the JSON objects. Can anyone enlighten me on how to achieve this? All suggestions are extremely appreciated. Thank you!

JSON:

[
    {"id":3,"title":"Some title 3"}
    {"id":4,"title":"This is title 4"}
]

Answer 1

You can use Array.prototype.find() to get only element of array where id of object is 4 . Iterate the result of .find() call.

let res = data.find(({id}) => id == 4);

Alternatively, if .find() is not defined, or object destructuring is not supported you can use .filter()

var res = data.filter(function(o) {
            return o.id == 4
          }).pop();

 let data = [{"id":1,"title":"Lorem Ipsum has been the industry's standard dummy text ever since the 1500s","body":[{"type":"plaintext","body":"Pork loin pastrami bresaola cupim kevin, meatball short ribs drumstick jerky andouille shankle.
