creating a JSON array within a function

Question

creating a JSON array within a function

I am currently developing an Angular application and working on a component with the following method:

createPath(node, currentPath = []){
  if(node.parent !==null) {
     return createPath(node.parent, [node.data.name, ...currentPath])
  } else {
    return [node.data.name, ...currentPath];
   } 
}

Within each node, I also have an id that can be accessed using node.data.id. My goal is to store this data in an array structured like this:

[{
 id:1, // accessed through node.data.id
 name:"myName"  // accessed through node.data.name from the above method.
}
]

This code snippet demonstrates an example of how the data should be formatted dynamically to account for any number of items during runtime.

To achieve this, I need to modify the existing code and incorporate this data structure within the same method. How can I accomplish this?

Have you checked if your array is being fetched from a different source? As it stands, the code provided only works for a single item. Consider utilizing forEach() and push to add elements into the array. This will ensure each item is included in the list rather than just the first one.

To begin, initialize an array to hold your JSON objects like this: arrayToHoldData = [ ]
Insert the following code wherever you need to populate the array (e.g. right before the return statement inside an else block):
```
this.arrayToHoldData.push(
 {
   id: currentNode.data.id,
   name: currentNode.data.name
 }
)
```
