[TIL] JavaScript: renaming variables during object destructuring

May 2, 2023·1 min readjavascript

TIL that it’s possible in JavaScript to rename variables at the moment of destructuring.

Let’s say you have an object user, previously fetched from an API, with snake_case property names.

However, you’d like variable names to be in lowerCamelCase.

You can do the following:

const { user_id: userId, age } = user;

Variable name is now userId.
