Single Code Path For Asynchronous Functions(gen5.info)

submitted by paul_houlepaul_houle(435) 3 years, 9 months ago

Sometimes a function that does an asynchronous action can return without doing asynchronous action: for instance, if an error occurs or it retrieves a value from a cache. If it calls the callback directly, this has a major impact on the flow of execution in the program and can cause subtle bugs to appear. By always initiating an asynchronous callback, you can avoid this problem.
