I want to delete a object on my objects array, but i cant find a better way than using some loop to do such a thing, on each object we have an ID
example:
var array = [{
id : String,
price : Number,
someOtherVars : String
}]
var element = {
id : "00dks",//this is a unic value
price : 12,
someOtherVars : "some value"
}
var element2 = {
id : "a43sdk",
price : 30,
someOtherVars : "some value"
}
var element3 = {
id : "0as0d",
price : 122,
someOtherVars : "some value"
}
array.push(element);
array.push(element2);
array.push(element3);
so... what is the most efficient way of doing this?
ps: i'm looking for a way to access the element by the key with out using any kind of loop, like the function .find(), example array["0as0d"], to get element3
Don't use an array, but a Map.
var map = new Map();
var element = {
id : "00dks",//this is a unic value
price : 12,
someOtherVars : "some value"
}
var element2 = {
id : "a43sdk",
price : 30,
someOtherVars : "some value"
}
var element3 = {
id : "0as0d",
price : 122,
someOtherVars : "some value"
}
map.set(element.id, element);
map.set(element2.id, element2);
map.set(element3.id, element3);
// later...
if (map.delete("0as0d")) {
console.log('delete successful');
}
console.log(map.size);Collected from the Internet
