Reduce multi-level array into object

Question

I have the following array:

[
    ["123", { keyOne: "val", keyTwo: "val2" }],
    ["402", { keyOne: "val123", keyTwo: "val233" }],
    ["542", { keyOne: "val", keyTwo: "val2" }],
];

And I need to turn it into an Object like this:

{
    "123": { keyOne: "val", keyTwo: "val2" },
    "402": { keyOne: "val123", keyTwo: "val233" },
    "542": { keyOne: "val", keyTwo: "val2" }
}

I think this should be done with reduce() , but I am not sure how.

Answer 1

You can use Object.fromEntries

const data = [
    ["123", { keyOne: "val", keyTwo: "val2" }],
    ["402", { keyOne: "val123", keyTwo: "val233" }],
    ["542", { keyOne: "val", keyTwo: "val2" }],
];

const result = Object.fromEntries(data);

console.log(result);
