Search in JSON array?

Question

JavaScript

There is 1 array:

variable:Array[1]
 0:Object
   articulus:"01-02-01"
   id:10
   quantity:99
   unique_id:1

And there is an article that always changes, for example 01-02-01

How to find an object with the same article in this array?

Answer 1

variable.filter(i=>i.articulus === '01-02-01');
Returns an array with objects of the corresponding article.
