Imagine you are building a flexible and dynamic front-end application that needs to fetch data from multiple sources. How would GraphQL be advantageous in this scenario?

In a scenario where a flexible and dynamic front-end application needs to fetch data from multiple sources, GraphQL is advantageous because it allows the client to specify the structure of the response, reducing over-fetching and under-fetching of data. This flexibility in querying makes it ideal for dynamic front-end applications.
