@babel/plugin-transform-object-rest-spread enables the use of object rest and spread syntax in JavaScript, transforming it into code compatible with older environments. This Babel plugin allows developers to leverage modern JavaScript features like ...rest and ...spread for cleaner and more concise code when dealing with objects, ensuring broader browser and Node.js support by transpiling the syntax down to ES5-compatible equivalents. It is a core element for modern JavaScript development workflows utilizing Babel.
