I am trying to add an array as one of my class properties, but I can't seem to find out how.
This is the code that I am currently trying.
export class Foo {
id: number;
value: number;
array: [];
}
I have searched online to try to find the answer with no avail, so I thought I would ask here.
You can do it in 2 different ways based on the Typescript documentation: https://www.typescriptlang.org/docs/handbook/basic-types.html
Once you have chosen the way you want to declare you array, you have to give it a type. Example: string, number, Observable, etc.
Example 1:
export class Foo {
id: number;
name: string;
array: number[]
}
Example 2:
export class Foo {
id: number;
name: string;
array: Array<number>;
}
export class Foo {
id: number;
value: number;
array: Array<>;
}
if you want an Array of specific type you can use for exemple:
array: Array<string> or array: Array<number> ...
You should define type items in that array. Some examples:
array: number[]
array: string[]
array: any[]
