# `replace()` The replace method behaves similarly to merge; however, in addition to overwriting matching items with string keys, the replace method will also overwrite items in the collection that have matching numeric keys: ```js const collection = collect({ name: 'Bob', }); const replaced = collection.replace({ name: 'John', number: 45, }); replaced.all(); // { // name: 'John', // number: 45, // } ``` [View source on GitHub](https://github.com/ecrmnn/collect.js/blob/master/src/methods/replace.js)
