Practical GraphQL - Become a GraphQL Ninja - Basic mutations – continued

The video tutorial covers the creation and testing of two new mutations: 'create car' and 'remove car'. It begins with a recap of the previous challenge and introduces the new task. The instructor demonstrates how to implement these mutations, including extracting necessary data and making adjustments to constants. The tutorial concludes with testing the mutations to ensure they function correctly, and verifying the results.

Why is it necessary to change 'constant cars' to 'let cars'?
