So I made a discord bot recently and I made a warning system,so basicly,I have my object(this is in mongodb btw):
{
_id: '0123',
warns: [
{
pos: 1,
reason: 'apples r blue'
},
{
pos: 2,
reason: 'apples r red'
}
]}
so the array is longer but i wanna keep it short,so basicly everytime a object in the array is deleted,i want each pos
to be updated,for example,i delete
{
pos: 1,
reason: 'apples r blue'
}
and i want the second object
{
pos: 2,
reason: 'apples r red'
}
pos's to be updated to 1,now this seems easy but i wanna do this for ALL objects,but lets say i have the array like this now:
warns: [
{
pos: 1,
reason: 'apples r blue'
},
{
pos: 2,
reason: 'apples r red'
},
{
pos: 3,
reason: 'apples r red'
},
{
pos: 4,
reason: 'apples r red'
},
{
pos: 5,
reason: 'apples r red'
}
]}
and lets say i suddenly removed the object with a pos of 3
,then i want 4 and 5 to be updated as well (4 becomes 3 and 5 becomes 4 and so on),i know how to update the objects but cant think of a method as its 5am right now and im tired,so i hope someone will suggest a method
Well, since you only want to know how to update values in an array, here it is:
array.map((value) => {
value.pos--;
return value;
};
