GraphQL is a way of asking for exactly the information you want from a website or program. It helps you get only the information that you need, instead of getting too much or too little. To use GraphQL, you write down a list of the information you want. Then, you send it to the website or program and it responds with the information you asked for. This way, you don't have to get information you don't need, and you can be sure that all your questions were answered.
