Adding to a nested array in angular

I have a data object model like the following:

export class JournalEntries {
  id?: number;
  year?: string;
  month: string;
  link?: string;
  months?: any;
}

A sample data would be:

"journalentries": [
    { 
      "id": "2000001",
      "year": "2021", 
      "months": [
        {
          "year": "2021", 
          "month": "January", 
          "link": "Jan_Feb_2021"
        },
        {
          "year": "2021", 
          "month": "February",
          "link": "Jan_Feb_2021"
        },
         ...
        {
          "year": "2021", 
          "month": "December",
          "link": ""
        }
      ]
    },
    { 
      "id": "2000002",
      "year": "2020", 
      "months": [
        {
          "year": "2020", 
          "month": "January", 
          "link": "Jan_Feb_2020"
        },
        {
          "year": "2020", 
          "month": "February",
          "link": "Jan_Feb_2020"
        },
        ...
        {
          "year": "2020", 
          "month": "December",
          "link": "Dec_2020"
        }
      ]
    },
 ]

My problem is, I can't seem to add a new month data to the nested array in the appropriate year. So if I add 2021, May, and some_link in the text boxes in the HTML part, it doesnt add it to the nested array. it adds it to the Main array. Which makes sense because this is what I have in the saveJournals click event

  this.journals.unshift( //putting it on the journals array
    {
      year: this.selectedRowData.year,
      month: this.selectedRowData.month,
      link: this.selectedRowData.link
    }
  )

So I get why it's doing that. But the following is coming up with an error

  this.journals.months.unshift( //Same with this.journals[].months.unshift
    {
      year: this.selectedRowData.year,
      month: this.selectedRowData.month,
      link: this.selectedRowData.link
    }
  )

I understand this could be a combination of problems, but I'm hoping someone knows the solution even with the vague data.

My expected goal is, if year already exist, add (year, month, link) to its months array else create year with new months array. Shooot! I'd be happy if you can help me with the unshift part only!

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
