I'm exploring ways to add more elements to an object, but I'm uncertain about the process.
My attempts to push data into the object have been unsuccessful.
people = [{
name: 'robert',
year: 1993
}];
//I aim to achieve this
people = {
name: 'joe',
year: 1992
}
//I want it to function as follows
people = [{
name: 'robert',
year: 1993
}, {
name: 'joe',
year: 1992
}];
I desire the capability to access it using people[0].name
To make the people variable an array of objects, you can do the following:
const people = [{ name: 'Alice', age: 30 }];
If you want to include a new object in the people array, you can use this code snippet:
const newPerson = { name: 'Bob', age: 25 };
people.push(newPerson);
To access specific objects or properties within the array, you can use these lines of code:
people[0];
people[0]['name'];
If you encounter any issues later on, it might be helpful to define the type for the people array as shown below:
export class AppComponent {
// your properties and methods
}
interface Person {
name: string;
year: number;
}
You can then declare your variables with the specified typings directly in your main code:
const people: Person[] = [{ name: 'Alice', age: 30 }];
const newPerson: Person = { name: 'Bob', age: 25 };
people.push(newPerson);
Give this a shot
people.push({ name: 'joe', year: 1992 });
