Convert an array of objects to a single object

This function converts an array of objects into a single object by using the Object.assign() method, which is used to copy values from one or more source objects to a target object.

JavaScript:

let arrToObj = arr => Object.assign({}, ...arr);

// Example
let arr = [{ a: 1 }, { b: 2 }, { c: 3 }];
console.log(arrToObj(arr)); // { a: 1, b: 2, c: 3 }

TypeScript:

let arrToObj = (arr: Array<Object>): Object => Object.assign({}, ...arr);

// Example
let arr = [{ a: 1 }, { b: 2 }, { c: 3 }];
console.log(arrToObj(arr)); // { a: 1, b: 2, c: 3 }
