if I have an array: [1,2,3,4] and another array of objects:
[{id:2, name:"Alexa"}, {id:1, name:"John"},{id:5 , name:"Mary"},{id:4, name:"Peter"} ],
how can I make an optimal function to sort based on the first array? result:
[{id:1, name:"John"},{id:2, name:"Alexa"},{id:4, name:"Peter"},{id:5, name:"Mary"} ]
I thank you very much for your attention.
Is this what you need?
const initialArr = [
{ id: 2, name: "Alexa" },
{ id: 1, name: "John" },
{ id: 5, name: "Mary" },
{ id: 9, name: "Zuzu" },
{ id: 3, name: "Mary" },
{ id: 4, name: "Peter" }
];
const arr = [1, 2, 3, 4];
initialArr.sort((a, b) => {
const getTypeIndex = (x) => arr.indexOf(x.id);
return getTypeIndex(a) - getTypeIndex(b) && a.id - b.id;
});
console.log(initialArr);
