zipObject

Combines two arrays, one of property names and one of corresponding values, into a single object.

This function takes two arrays: one containing property names and another containing corresponding values. It returns a new object where the property names from the first array are keys, and the corresponding elements from the second array are values. If the keys array is longer than the values array, the remaining keys will have undefined as their values.

Signature

function zipObject<P extends string | number | symbol, V>(keys: P[], values: V[]): { [K in P]: V };

Parameters

• keys (P[]): An array of property names.
• values (V[]): An array of values corresponding to the property names.

Returns

({ [K in P]: V }): A new object composed of the given property names and values.

Examples

import { zipObject } from 'js-utils-es/array';

const keys = ['a', 'b', 'c'];
const values = [1, 2, 3];
const result = zipObject(keys, values);
// result will be { a: 1, b: 2, c: 3 }

const keys2 = ['a', 'b', 'c'];
const values2 = [1, 2];
const result2 = zipObject(keys2, values2);
// result2 will be { a: 1, b: 2, c: undefined }

const keys3 = ['a', 'b'];
const values3 = [1, 2, 3];
const result3 = zipObject(keys3, values3);
// result3 will be { a: 1, b: 2 }
