How does lodash.create work?

In the lodash library, lodash.create is a function that creates a new object with the specified prototype object and properties. The function takes two arguments: the first argument is the prototype object to use for the new object, and the second argument is an optional object containing properties to add to the new object. The lodash.create function works by first creating a new object with no properties using the Object.create method, and then adding any specified properties to the new object using the Object.defineProperties method. If no properties are specified, the function simply returns the new object with the specified prototype object. Here's an example implementation of lodash.create that demonstrates how the function works: javascript Copy code {{{{{{{ function create(proto, properties) { const obj = Object.create(proto); if (properties) { Object.defineProperties(obj, properties); } return obj; } In this example, we define a function create that takes two arguments: proto and properties. We first create a new object obj using Object.create(proto), which creates a new object with the specified prototype object. We then check if properties is defined, and if so, we use Object.defineProperties(obj, properties) to add the specified properties to the new object. Finally, we return the new object obj with the specified prototype and properties. Overall, lodash.create provides a convenient way to create new objects with a specified prototype object and properties, allowing you to quickly create new objects that inherit properties from an existing object.

console.log(assignWith); // => { 'a': 1, 'b': 2, 'c': 3 }


const at = _.at({ 'a': [{ 'b': { 'c': 3 } }, 4] }, ['a[0].b.c', 'a[1]']);
console.log(at); // => [3, 4]


const create = _.create({ 'a': 1 }, { 'b': 2 });
console.log(create); // => { 'a': 1, 'b': 2 }


const defaults = _.defaults({ 'a': 1 }, { 'b': 2 }, { 'a': 3 });
console.log(defaults); // => { 'a': 1, 'b': 2 }

const _ = require("lodash");

const proto = {
  greet() {
    console.log(`Hello, ${this.name}!`);
  },
};

const obj = _.create(proto);
obj.name = "Alice";

obj.greet(); // Logs "Hello, Alice!"

In this example, we first import the lodash library and assign it to the variable _. We then define an object proto that has a single method greet, which logs a greeting to the console using the name property of the object. We then call _.create(proto) to create a new object obj with proto as its prototype. We set the name property of the new object to 'Alice'. Finally, we call the greet method on the obj object, which logs the message "Hello, Alice!" to the console, demonstrating that the obj object inherits the greet method from its prototype object proto. Overall, lodash.create provides a convenient way to create new objects with a specified prototype object, allowing you to easily inherit methods and properties from an existing object.
