- Asynchronous vs synchronous execution. What is the difference?
SYNCHRONOUS EXAMPLE: Any process consisting of multiple tasks where the tasks must be executed in sequence, but one must be executed on another machine (Fetch and or update data, get a stock quote from financial service, etc ) If it's on a separate machine it is on a separate thread, whether synchronous or asynchronous
- webserver - What is the difference between asynchronous and synchronous . . .
Synchronous Asynchronous communication has nothing to do with application waiting or not for resources Synchronous communication is when communication looks like ping-pong one request and one response in that particular order Asynchronous communication is when there could be multiple requests and responses could return in random order
- Using resolved promise data synchronously - Stack Overflow
I want to know if there is any way at all to use the data from a resolved promise in 'normal' synchronous code There isn't a way to write completely synchronous code when handling asynchronous responses Once any operation is asynchronous, you have to deal with the response using asynchronous techniques and cannot program with it synchronously You must learn to program asynchronously The two
- Is there any reason to use a synchronous XMLHttpRequest?
Synchronous calls block the browser which leads to a terrible user experience Thus my question I couldn't think of any good reason to use it
- What is the difference between Asynchronous calls and Callbacks
The problem with synchronous callbacks is they can appear to "hang" The problem with asynchronous callbacks is you can lose control of "ordering" - you can't necessarily guarantee that "A" will occur before "B" Common examples of callbacks include: a) a button press handler (each different "button" will have a different "response")
- When to use Task. Delay, when to use Thread. Sleep?
It's synchronous In the thread, you can't really do anything other than waiting for the delay to finish As for real-life usage, I have been programming for 15 years I have never used Thread Sleep() in production code I couldn't find any use case for it Maybe that's because I mostly do web application development
- Setting XMLHttpRequest. responseType forbidden all of a sudden?
This is correct behaviour, as defined in the Specification of XMLHttpRequest: When set: throws an "InvalidAccessError" exception if the synchronous flag is set and there is an associated XMLHttpRequest document The responseType property cannot be set when the XMLHttpRequest is not async, that is, synchronous Setting the third parameter of open to false causes the request to be synchronous
