When using asynchronous programming we can execute multiple tasks at the same time, but when using synchronous programming we can only execute one task at a time.
For different stakeholders, asynchronous and synchronous methods both offer advantages.
Async languages tend to be quicker than synchronous languages. One of the most important decisions you will have to make when writing software is deciding how to handle asynchronous programming - will your code be synchronous or asynchronous? The decision can have a big impact on your application.
If you need to use multiple threads, most languages with asynchronous code must be implemented as such. Java is one of the few languages that supports both asynchronous and synchronous programming.
It's a good choice if you need to use both types of code at the same time, but it can be difficult to reason about code that uses asynchronous calls. Python has a module that allows you to write code that is synchronized with the GIL.
It is a good choice for tasks that require high performance, but it can be hard to read and maintain. There is a module that allows you to write code that is synchronized with the GIL.
Ruby is a good choice for tasks that require high performance, but it can be hard to read and maintain. Javascript does not have a module that is asynchronous. This can make code more difficult to read and maintain, but it also makes sense for tasks that don't need high performance.
It is important to consider the pros and cons of different types of code.
Is phone synchronous or asynchronous?
The main difference between asynchronous and synchronous communication is that they are scheduled, real-time interactions by phone, video, or in-person. Asynchronous communication can happen on your own time.
Data consistency and architectural simplicity are what asynchronous communication trades. Asynchronous designs give better control over failures. If you want to maximize the speed of evolution and switch to asynchronous communications once your architecture grows, start with a synchronous system.
In some cases, asynchronous communication can be less engaging than synchronous communication.
