+**Best Practice** Write variable names in JavaScript in camelCase. In camelCase, multi-word variable names have the first word in lowercase and the first letter of each subsequent word is capitalized. diff --git a/curriculum/challenges/english/05-apis-and-microservices/mongodb-and-mongoose/chain-search-query-helpers-to-narrow-search-results.md b/curriculum/challenges/english/05-apis-and-microservices/mongodb-and-mongoose/chain-search-query-helpers-to-narrow-search-results.md index 210e970019..12be099f8a 100644 --- a/curriculum/challenges/english/05-apis-and-microservices/mongodb-and-mongoose/chain-search-query-helpers-to-narrow-search-results.md +++ b/curriculum/challenges/english/05-apis-and-microservices/mongodb-and-mongoose/chain-search-query-helpers-to-narrow-search-results.md @@ -14,15 +14,6 @@ If you don’t pass the callback as the last argument to `Model.find()` (or to t Modify the `queryChain` function to find people who like the food specified by the variable named `foodToSearch`.
