Manipulate JSON objects using AngularJS to filter an array based on its unique identifier rather than its index position

Question

Manipulate JSON objects using AngularJS to filter an array based on its unique identifier rather than its index position

Is there a way to filter this JSON data by an element (in this case the id) without relying on the index?

     ABC: [{
 ID: home,
 elementsHome: [
       {
       el1: x,
       el2: y},
       {
       el3: d,
       el4: s}]
  },
  {
  ID: payments,
  elementsPaymets: etc...
  }];

An HTML structure with an ng-repeat like the one below doesn't seem to work: ng-repeat: item in ABC.element2 | filter: {id:"good"}. The only workaround I have found is rewriting ABC as ABC[0], but I am looking for a solution that avoids this. Any help would be greatly appreciated.

Thank you!

XYZ.filter((element) => {
  return element.name === 'whatever you need to verify'
})

The filter method in JavaScript is used to iterate through an array and create a new array with elements that pass a certain condition defined by a provided function. This function takes the current element, index, and array as arguments, and should return either true or false. If the condition returns true for an element, it is included in the new array.

You can learn more about the filter method here.

Correction

It seems like you are looking to locate a specific item in an array and access one of its properties. If you already know the identifier:

let searchId = 'EXAMPLE'

You can simply find the item containing that id:

let selected = XYZ.find(function(element) {
  return element.id === searchId
})

If a match is found, you can retrieve the desired property value:

selected && selected['details' + searchId.substr(0, 1) + searchId.substr(1).toLowerCase()]
