How does lodash.assign work?

lodash.assign is a function that can be used to copy the values of all enumerable properties from one or more source objects to a target object. The function takes one or more objects as arguments, where the first argument is the target object that will receive the copied properties, and any subsequent arguments are the source objects that will be used to copy properties from. If two or more objects have properties with the same name, the value of the property in the last object will overwrite the value of the property in the previous object(s). Here's an example of how lodash.assign can be used: javascript Copy code {{{{{{{ const { assign } = require('lodash'); const target = { a: 1, b: 2 }; const source = { b: 4, c: 5 }; const result = assign(target, source); console.log(target); // Output: { a: 1, b: 4, c: 5 } console.log(result); // Output: { a: 1, b: 4, c: 5 } In this example, we use lodash.assign to copy the properties of source to target. We then log the value of target and result to the console. After running this code, the value of target is { a: 1, b: 4, c: 5 }, which means that the value of the b property has been overwritten by the value in the source object. The value of result is the same as target, since lodash.assign modifies the target object in place and returns a reference to it. Overall, lodash.assign is a useful function for copying properties between objects in JavaScript, and can be used to create more flexible and reusable code.

const { assign } = require("lodash");

const target = { a: 1 };
const source = { b: 2 };

const result = assign(target, source);

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

In this example, we create two objects called target and source. We then use lodash.assign to copy the properties from source to target, and store the result in a new variable called result. After running this code, the value of result is { a: 1, b: 2 }, which means that lodash.assign has successfully copied the properties from source to target. Using lodash.assign can be useful in situations where you need to combine the properties of multiple objects into a single object, or when you need to modify an existing object with new properties.
