How JS is single threaded and asynchronous?
Synchronous with a single thread : Tasks are executed one after another. Each task waits for its previous task to get executed. … Asynchronous with a single thread : Tasks start being executed without waiting for a different task to finish. At a given time, only a single task can be executed.
Non-Blocking: It refers to the program that does not block the execution of further operations. Non-Blocking methods are executed asynchronously. Asynchronously means that the program may not necessarily execute line by line.
