Viewsfill remaining indexes in array with null values
I need to adjust for blank days in my calendar app. There should be 35 blocks to make up the calendar, but I need to fill the array with 30 items inside of that. Is there a method that allows that?
so far this just pushes the days, but you will notice the last days stretch. How can I get blank days in my array? I think i need ensure the calendar is always 35 items.
So I want [null, null, 0, 1, 2, 3, 4, 5...last day in month]. almost like flex end.
Example:
var monthIndex = 0;
var calendarDays = [];
var daysInMonth = [31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, 31];
function updateCalendar() {
calendarDays = [];
for (let i = 0; i < daysInMonth[monthIndex]; i++) {
calendarDays.push(i);
}
},

You can use #Array.fill and then map in the values, like
new Array(35).fill(" ").map((_, i) => i <= daysInMonth[monthIndex] ? i : '')
var calendarDays = [];
var daysInMonth = [31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, 31];
function updateCalendar(monthIndex) {
calendarDays = new Array(35).fill(" ").map((_, i) => i <= daysInMonth[monthIndex] ? i : '');
return calendarDays;
}
console.log(updateCalendar(0))
console.log(updateCalendar(1))
