How to declare a javascript array that will receive a JSON array

Question

Given the interface:

export interface Pergunta {
    id: number
    titulo: string
    opcoes:[]
}

I want the options array to receive its options array:

{
    "id": "1",
    "titulo": "Qual o seu comportamento em relação aos seus investimentos?",
    "opcoes": [
      {
        "description": "Preservar meu dinheiro sem correr risco"
      },
      {
        "description": "Ganhar mais dinheiro, assumindo riscos moderados"
      },
      {
        "description": "Ganhar mais dinheiro, assumindo riscos agressivo"
      }
    ]
  },

Answer 1

export interface Pergunta {
    id: number;
    titulo: string;
    opcoes: Opcao[];
}

export interface Opcao {
    description: string;
}

This would be the most correct way to receive your data

Answer 2

I believe the best solution is for you to type the attribute array options. In some cases when you don’t do this process, you can use a array of any. For example:

public opcoes: Array<any>;

However I believe that the best solution to your problem would be something like this:

export interface Pergunta {
    public id: number
    public titulo: string;
    public opcoes: Array<TipoDeOpcoes>;   } 

    export interface TipoDeOpcoes {
            public description: string   
}
