How does lodash.defaults work?

lodash.defaults is a function in the Lodash library that sets default values for undefined object properties.

When lodash.defaults is called with an object and one or more default objects, it performs the following steps:

It creates a new object with the properties of the original object and the default objects.
For each property in the new object, it checks if the property value is undefined.
If the property value is undefined, it replaces it with the corresponding property value from the default object.

By defaulting to values of a given property, lodash.defaults ensures that an object always has the necessary properties, even if they are not explicitly defined.

lodash.defaults can be useful for ensuring that objects have default values for properties that may not always be explicitly set, or for merging multiple objects with a common set of properties.

Overall, lodash.defaults is a powerful tool for working with objects in JavaScript, allowing developers to more easily manage the state of their applications.

const _ = require("lodash");

const user = {
  name: "John Doe",
  email: "johndoe@example.com",
};

const defaults = {
  name: "Jane Doe",
  phone: "555-555-5555",
};

const newUser = _.defaults(user, defaults);

console.log(newUser);

In this example, we're using the lodash library to set default values for an object. We're first creating an object called user with two properties: name and email. We're then creating another object called defaults with two properties: name and phone. We're then using _.defaults to merge the user object with the defaults object. If any properties in user are undefined, _.defaults will set them to the corresponding property value in defaults. Finally, we're using console.log to output the resulting object to the console. When we run this code, we'll get output that looks something like this: css Copy code
