Ideally, we will focus on three major programming models, which are as follows:
The first one is a single-threaded synchronous model
The second one a is multithreaded model
The third one is an asynchronous programming model
Since JavaScript employs an asynchronous model, we will discuss it in greater detail. However, let's start by explaining what these programming models are and how they facilitate their end users.
The single-threaded synchronous model is a simple programming model or single-threaded synchronous programming model, in which one task follows the other. If there is a queue of tasks, the first task is given first priority, and so on and so forth. It's the simplest way of getting things done, as shown in the following diagram:
The single-threaded synchronous programming model is one of the best examples of a Queue
data structure, which follows the First In First Out (FIFO) rule. This model assumes that if Task 2 is being executed...
