Is there a way in JavaScript to determine if an item already exists in an array? I am using the following code to add items to my array:
const booked_hours = [];
for (let i = 0; i < apptid_set.size; i++) {
const book_hours = [...book_times][i].split(" ");
booked_hours.push(book_hours[2]);
}
//alert(booked_hours);
The code works fine, but I want to ensure that there are no duplicate items in 'booked_hours'. Any suggestions on how to achieve this?
If you're unsure about the content being added to the scheduled_times array, this solution may need some adjustments, but here's a suggestion for you to consider.
const scheduled_times = [];
for (let j = 0; j < apptid_list.length; j++) {
const sched_time = [...appt_times][j].split(" ");
if (!scheduled_times.includes(sched_time[2])) {
scheduled_times.push(sched_time[2]);
}
}
If you're looking to optimize your code for managing booked hours, consider utilizing a set instead of an array.
const booked_hours = new Set();
for (let i = 0; i < apptid_set.size; i++) {
const book_hours = book_times[i].split(' ');
booked_hours.add(book_hours[2]);
}
To easily convert the set back to an array, simply use [...booked_hours]
