I have an object that has multiple keys and each of these keys has an array storing multiple elements. I want to be able to remove a specified element from the key's array.
I have tried using the delete keyword as well as the filter method, but I have been unsuccessful. I'm a total newbie to JS so I appreciate any assistance. Also, I want to do this using ONLY JavaScript, no libraries.
Here is the code where I am creating my object:
function add(task, weekdayDue) {
let capitalWeekday = weekdayDue.charAt(0).toUpperCase() +
weekdayDue.slice(1);
if (toDoList[capitalWeekday] === undefined) {
let subArr = [];
toDoList[capitalWeekday] = subArr.concat(task);
} else {
toDoList[capitalWeekday].push(task);
}
}
and here is the code as I have it now. Clearly it is not producing the correct result:
function remove(task, weekdayDue) {
let capitalWeekday = weekdayDue.charAt(0).toUpperCase() +
weekdayDue.slice(1);
delete toDoList.capitalWeekday[task]
//the below code is working; i want to send this to another
array
if (archivedList[capitalWeekday] === undefined) {
let subArr = [];
archivedList[capitalWeekday] = subArr.concat(task);
} else {
archivedList[capitalWeekday].push(task);
}
};
add('laundry', 'monday');
add('wash car', 'monday');
add ('vacuum', 'tuesday');
add('run errands', 'wednesday');
add('grocery shopping', 'wednesday');
// the output is: { Monday: [ 'laundry', 'wash car' ],
Tuesday: [ 'vacuum' ],
Wednesday: [ 'run errands', 'grocery shopping' ] }
Then let's say I want to remove 'wash car' from Monday I was trying:
remove('wash car', 'monday');
console.log(toDoList)
// The output is an empty object {}
