Transform arrays to objects

This article explains how you can change arrays to an array of objects

Let's say, you want to change the following data from arrays to objects:

{
  "categories": [

      "name": "concrete"
    },
    {
      "name": "posts"
    },
    {
      "name": "system"
    }
  ]
}
