babel-plugin-syntax-object-rest-spread

What is babel-plugin-syntax-object-rest-spread?

The babel-plugin-syntax-object-rest-spread package allows Babel to parse the object rest/spread syntax. This syntax feature lets you copy enumerable properties from one object to another using the spread (...) operator and pick up remaining properties that are not explicitly picked up by the destructuring pattern using the rest (...) operator.

What are babel-plugin-syntax-object-rest-spread's main functionalities?

Object Spread

Allows an object's own enumerable properties to be copied into a new object. Useful for creating a shallow copy of an object or combining multiple objects into one.

{ ...source }

Object Rest

Allows the remaining own enumerable property keys that are not already picked off by the destructuring pattern to be collected into an object.

{ a, b, ...rest } = object

babel-plugin-transform-object-rest-spread

This is a legacy plugin that was used to transform object rest and spread properties for Babel 6. It has been superseded by @babel/plugin-proposal-object-rest-spread in Babel 7.
