In what scenario would you use the "await" keyword?

Using the "await" keyword is specifically relevant in scenarios where asynchronous operations are conducted, such as when fetching data from a database. The "await" keyword can only be used inside an async function and it pauses the execution of the function until the Promise it is waiting on is resolved or rejected. This asynchronous nature allows for more efficient handling of operations that might otherwise block the execution thread while waiting for resources, like database responses.

When fetching data from a database, using "await" ensures that the program will wait for the database to return the requested data before proceeding with the next line of code. This can lead to cleaner, more readable code since it avoids the need for complex chains of callbacks or then() statements which are often harder to manage and understand. This approach helps in maintaining the flow of the code similar to synchronous programming while still benefiting from the non-blocking nature of asynchronous operations.

In contexts like synchronous function calls, loop iterations, or immediate function executions, using "await" wouldn’t make sense, since those scenarios do not inherently involve Promises or asynchronous behavior.
