What is the difference between graphqlExpress and graphqlHTTP?

Question

Express.js

Hello everyone, what is the difference between using

graphqlExpress

app.use(
  '/graphql',
  graphqlExpress({
    schema: MyGraphQLSchema,
    graphiql: true,
  }),
);

from

graphqlHTTP

app.use(
  '/graphql',
  graphqlHTTP({
    schema: MyGraphQLSchema,
    graphiql: true,
  }),
);

UPD: Since I understood, thanks
