GraphQL is a query language used mainly to download data from a server. It allows to specify the required data precisely, simplifies data aggregation, and uses the type system for data specification. In other words, GraphQL is a smart mediator between a client and data sources.
Moreover, a client can take only one request action instead of a few ones to get results for different needs. This language is beneficial in many ways and solves problems that front-end developers face on a daily basis. This technology helps us to please clients with the most effective solutions and create highly-competitive websites and applications.
