I am struggling to include an array as a property in one of my classes, but I am unable to figure out the correct way to do it.
Below is the snippet of code that I am currently experimenting with:
export class Foo {
id: number;
value: number;
array: [];
}
After conducting extensive research online and coming up empty-handed, I decided to seek help here. Can anyone provide guidance on how to correctly add an array property to a class?
If you're looking to declare an array in Typescript, there are two methods outlined in the official Typescript documentation: https://www.typescriptlang.org/docs/handbook/basic-types.html
Once you've decided on your preferred declaration method, don't forget to assign a type to your array. This could be string, number, Observable, or any other relevant data type.
Here's an example using Method 1:
export class Foo {
id: number;
name: string;
array: number[]
}
And here's an example using Method 2:
export class Foo {
id: number;
name: string;
array: Array<number>;
}
class Bar {
identifier: string;
quantity: number;
list: Array<>;
}
To define an array with a specific data type, you can do so by specifying it like this:
list: Array<boolean> or list: Array<date> ...
It is important to specify the type of items in the array. Here are a few examples:
array: number[]
array: string[]
array: any[]
