In JavaScript, functions are first-class citizens, meaning they can be assigned to variables, passed as arguments, and returned from other functions. A higher-order function is a function that takes one or more functions as arguments or returns a function as a result.

   function createMultiplier(multiplier) {
       return function(value) {
           return value * multiplier;
       };
   }

   const double = createMultiplier(2);
   console.log(double(5)); // Output: 10

In this example, the await keyword pauses the execution of the fetchData function until the promise is resolved, making the code easier to understand.

Handling Errors with Async/Await:

• An async function must be executed within an async context.
• The async function returns a Future, which is a lazy value that does nothing until awaited.

The await keyword is used to pause the execution of an async function until the Future it is working on completes. This allows other tasks to run concurrently while waiting for the result.
