How to Rename Fields When Using Object Destructuring

Learn how to rename an object field while using object destructuring.

Sometimes, when working with an object, you may come across a situation where you want to destructure it but also change the names of some of its properties. This can be useful if the original property name does not align with your naming convention or if you already have a variable with the same name.

To rename a field while destructuring an object, you can use the following syntax:

const person = {
  firstName: 'Tom',
  lastName: 'Cruise'
}

const { firstName: name, lastName } = person

name // 'Tom'
lastName // 'Cruise'

By specifying firstName: name, we are renaming the firstName field of the person object to name in the destructuring assignment. Now, we can access the renamed field using the name variable.

Using object destructuring with field renaming allows for more readable and concise code, making it easier to work with complex objects and their properties.

Remember to only rename fields that are necessary for your specific use case, and keep the purpose of the property clear to maintain code clarity.
