Lodash _.zipObject

Overview

The lodash _.zipObject() method creates an object from an array of property identifier keys and an array of corresponding property value data. It takes two arguments: the first argument is an array of strings or symbols used as keys in the resulting object, and the second argument is an array of values or functions to be assigned to the corresponding keys in the resulting object.

If only one array is passed as an argument, the method returns an object with properties created using array items as keys and undefined as values. If an item in the array of property value data is also an array, it will be flattened into a single value or function.

The resulting object will always have a property for each key in the keys argument, even if the corresponding value is undefined.

For example:

const keys = ['a', 'b', 'c'];
const values = [1, 2, 3];
const result = _.zipObject(keys, values);

console.log(result);
// Output: {a: 1, b: 2, c: 3}

In the above example, the keys array is used as property keys in the resulting object, and the values array is assigned to the corresponding properties.

The method can also be used with nested arrays, such as:

const keys = [['firstName', 'lastInitial'], 'age'];
const values = [['John', 'Doe'], 30];
const result = _.zipObject(keys, values);

console.log(result);
// Output: {{firstName: 'John', lastInitial: 'D', age: 30}}

In this example, the first key is an array consisting of two string elements, which are used to create nested properties in the resulting object. The second key is a string, which is used to create a regular property in the resulting object.

To summarize, the _.zipObject() method is a powerful tool for creating objects from arrays of property identifiers and values. It can be used with nested arrays and is flexible enough to handle any type of data that can be stored in an object property.
