In synchronous operations tasks are performed one at a time and only when one is completed, the following is unblocked. In other words, you need to wait for a task to finish to move to the next one. In asynchronous operations, on the other hand, you can move to another task before the previous one finishes.
What is difference between asynchronous and synchronous?
Synchronous = happens at the same time. Asynchronous = doesn’t happen at the same time. With synchronous learning, participants can receive immediate feedback. With asynchronous learning, the participants can learn at their own pace.
Asynchronous is the “opposite” of synchronous. Functions and processes will run independently and parallel to each other – They don’t wait nor depend on each other. To define an asynchronous function, we simply add async in front. That’s all. But take note that async function will return a promise instead of the results directly.
What happens when a synchronous request is made?
How is an asynchronous request not blocked by the browser?
