Creating an array in Angular is done by using the syntax []

I encountered an error and I'm not sure how to fix it. Can someone assist me?

The error message reads: "Type '{ animal:[{ id : 1,name: "Elephant"},{id : 2, name: "Horse"} []; }' is not assignable to type 'string[]'. Property 'includes' is missing in type '{ animal: { id: number; name: string; }[]; }'."

 animals : string[];
 ...

 let e = {
      animal:[
      { 
        id : 1,
        name: "Elephant"

      },
      {
        id : 2,
        name: "Horse"
      }
    ]};
    this.animals = e;

Answer №1

If we were to keep the value of e unchanged, the category of creatures would appear as:

creatures: {creature: [{id:number, name:string}]}

Attempting to place this type into a string array is currently what you are doing, resulting in something like ['Lion', 'Tiger']. For more information on creating your own type, check out this question.
