I think it looks ok and it works ok
Johny Sins
@JohnySi73551906_twitter

can someone tell me why

var arr = new Object();
    arr.first = "lorem";
    arr.last = "ipsum";
    console.log(arr.hasOwnProperty('first'));

returns true

but

var Arr = [{first: "lorem", last: "ipsum"}];
    console.log(Arr.hasOwnProperty('first'));

returns false

Victor Popescu
@VicPopescu
@JohnySi73551906_twitter because arr is an object and Arr is an array
console.log(Arr[0].hasOwnProperty('first'));
you do a for to iterate each object inside the array
Johny Sins
@JohnySi73551906_twitter
ok
Victor Popescu
@VicPopescu
if you have only 1 object inside the array you can use the [index] to access it, but if the number of objects is random or unknown you need a for loop

@VicPopescu hello! do you know how can i compare two values of different properties?
var arr = [{first: "lorem", last: "ipsum"}, {first: "dolor", last: "sit"}];
Aditya
@ezioda004
@JohnySi73551906_twitter You want to compare first property of both objects in array?
Johny Sins
@JohnySi73551906_twitter
something like that, yes
Victor Popescu
@VicPopescu
@JohnySi73551906_twitter of different properties on the same object?
Johny Sins
@JohnySi73551906_twitter
different
objects
Victor Popescu
@VicPopescu
oh, then you need a double iteration
inside your array for loop, for each iterated object, you do another for to loop through all the rest of the objects
and there you compare
Johny Sins
@JohnySi73551906_twitter
I'll try
Victor Popescu
@VicPopescu
alright try it and let us know
Johny Sins
@JohnySi73551906_twitter
@VicPopescu I can't get it to find objects with same properties
[ 'first', 'last' ]
[ 'last' ]
for(var i = 0; i < collection.length; i++) {
        if(Object.keys(collection[i]) === Object.keys(source)) {
            console.log('este ba!');
        } else {
            // console.log('nu este!');
            console.log(Object.keys(collection[i]));
        }
    }

try to use let keyword may be
Markus Kiili
@Masd925
@JohnySi73551906_twitter You need a nested loop (or iteration) over source's keys. Looped object's keys are of no interest here.

Hello guys
I just have a simple question regarding using for loops and bootstrap columns

<div class="container">
    <div class="row">
        <div class="col-md-3 col-sm-6">        

<ul>

@for ($i = 0; $i < count($info->video); $i++)  

        <li>    

     <div class="card">
    <img class="card-img-top" src="{{$info->video[$i]->thumbnail}}" alt="Card image cap">
    <div class="card-body">
      <h5 class="card-title">{{$info->video[$i]->title}}</h5>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>

         </li>

@endfor

</ul>

    </div> 
</div>
here my code snippet
so I am retrieving data from the back end and displaying it , I just want to display 4 cards / row instead of 1 card
and I am a little bit confused
where to place the bootstrap col-classes
inside or outside the for loop ? so it can display 4 cards / row
Thanks in advance :)

@sjames1958gm
@Gallad23 Do you have to use ul / li ?
Not sure which templating language this is?
