How to create an array of days starting with today and going back the last 30 days in TypeScript

Answer 1

function getLast30Days(): number[] {
    const days: any[] = [];
    const today: Date = new Date();

    for (let i: number = 0; i < 30; i++) {
        const day: Date = new Date(today);
        day.setDate(today.getDate() - i);
        days.push(day.getDate()); // Get only the day of the month
    }

    return days;
}

console.log(getLast30Days());



/*
run:

[10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 31, 30, 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12]
