struggles with integrating arrays into object attributes in JavaScript

When working with object attributes, keep in mind that they only hold the first element of the assigned value

let groupedDepActivities=[]
 groupedDepActivities.push({
            id:1,
            term_activity:{
              terms:[{id:1},{from:'here'},{to:'there'},]
            }
          })

If you use console.log(), the result will show: * term_activity: terms: Array(1) 0: id: "1" [[Prototype]]: Object length: 1 * Remember, the terms attribute only holds the first element(id:1) of the array, not all elements

Answer №1

Although the console might cut off the output, your code is functioning as intended.

let groupedDepActivities = []
groupedDepActivities.push({
  id: 1,
  term_activity: {
    terms: [{
      id: 1
    }, {
      from: 'here'
    }, {
      to: 'there'
    }, ]
  }
})

console.log(groupedDepActivities);

Output:

[
  {
    "id": 1,
    "term_activity": {
      "terms": [
        {
          "id": 1
        },
        {
          "from": "here"
        },
        {
          "to": "there"
        }
      ]
    }
  }
]

Did you mean for terms to be a single object?

let groupedDepActivities = []
groupedDepActivities.push({
  id: 1,
  term_activity: {
    terms: {
      id: 1,
      from: 'here',
      to: 'there',
    }
  }
})

console.log(groupedDepActivities);

[
  {
    "id": 1,
    "term_activity": {
      "terms": {
        "id": 1,
        "from": "here",
        "to": "there"
      }
    }
  }
]

Answer №2

When you are manipulating your data, keep in mind that you are only interacting with one specific object:

{
    id:1,
    term_activity:{
    terms:[{id:1},{from:'here'},{to:'there'},]
    }
}

It is important to differentiate between an object represented by curly braces {}, and an array represented by square brackets []. To explore further into your data structure, you can use commands like:

console.log(groupedDepActivities=[0].term_activity.terms[0])

You may find it helpful to enclose the item you are logging in braces as well, which will display it as an object with distinct names in the console, for example:

console.log({groupedDepActivities})

If looking at variable names while you analyze them helps you understand their contents better, feel free to do so :)
