How do i convert an array of objects into 1 object in typescript [duplicate]

Question

I have an array of objects like this:

myArray = [
    {itemOneKey: 'itemOneValue', itemTwoKey: 'itemTwoValue'},
    {itemThreeKey: 'itemThreeValue'}
];

I wish to turn it to a single object like this:

myObject = {
    itemOneKey: 'itemOneValue',
    itemTwoKey: 'itemTwoValue',
    itemThreeKey: 'itemThreeValue'
}

in TypeScript. Anyone have a clue how I can go about to achieve this?

Note that if keys are repeated in the objects in your array (like if two objects have a property "itemKey"), then the result object will have only one value for that key. — Pointy

You can use Object.assign with spread syntax to merge all the objects.

const myArray = [
    {itemOneKey: 'itemOneValue', itemTwoKey: 'itemTwoValue'},
    {itemThreeKey: 'itemThreeValue'}
];
const res = Object.assign({}, ...myArray);
console.log(res);
