    Arrays in TypeScript

    Source

    You can declare arrays in TypeScript using the below methods.

    let numbers: number[] = [];

    Or you could do this

    let moreNumbers: Array<number>;
moreNumbers = [];

    In the second example, you have to make sure you assign it after you declare it before using the array. By assign I mean the second line, moreNumbers = []. You need to assign a value before you begin manipulating the array.

    Also remember, if you are using const like this.

    const moreNumbers: Array<number> = [];

    You need to make sure you're assigning the value in the first line. Like we have it above.
