How to get the first and last day of the current month in Angular 8?

I have a simple web application using Angular. I need to get the first and last date of the current month to set the value for a combobox datetime picker. I try as below but I can't get the last date of the current month.

 currentDate = new Date();
ngOnInit() {
    const firstDay = 1;
    const lastDay = currentDate.getDate(); // only return current date

The lastDay variable always returns to the current day, it's not the last day of the month.

Please help me if you have any solutions.

    It depends on the constructor of the Date. To get the last day of the current month you can do as below:

     currentDate = new Date();
    lastDate = new Date(this.currentDate.getFullYear(),this.currentDate.getMonth() + 1, 0,23,59,59,999);
    ngOnInit() {
        const firstDay = 1;
        const lastDay = this.lastDate.getDate(); 

    Notice that :

    getFullYear(): return from 1000 - 9999.

    - getMonth(): Return from 0 - 11.

    - getDate():  Returns the day of the month from 1 to 31.
