# `flip()` The flip method swaps the collection's keys with their corresponding values: ```js const collection = collect({ name: 'Sadio Mané', number: 10, }); const flipped = collection.flip(); flipped.all(); // { // 'Sadio Mané': 'name', // '10': 'number', // } ``` [View source on GitHub](https://github.com/ecrmnn/collect.js/blob/master/src/methods/flip.js)
