I have an array like this:

[{"this":"that","int":5},{"this":"that","int":5}]

How can I count the number of objects({}) inside of an array with Javascript?

Thanks in advance.

• javascript
• arrays
• object
• count

• 1 with Array#length? or do you mean the object? – Nina Scholz Commented Mar 2, 2016 at 18:17
• 1 Were you really not able to look up the Array.prototype.length property? – Omri Aharon Commented Mar 2, 2016 at 18:19

[{"this":"that","int":5},{"this":"that","int":5}].length; // 2

Try,

var cnt = 0;
var arr = [5 , 3 , "not an object" , {"this":"that","int":5},{"this":"that","int":5}];

arr.forEach(function(itm){
 if(!itm.__proto__.__proto__){
  cnt++;
 }
});

console.log(cnt + "normal objects are there"); //2

var length = arrayName.length;

Simply like this:

var yourArrayName = arrayName.length 

As when you have an array and use the .length it counts how many objects there are in the array.

Object {} inside array [] treated as items so you find the length of array to count the item(s)

var $data=[{"this":"that","int":5},{"this":"that","int":5}];

    var count=$data.length
