It is a dynamic language with a lot of potential and can be used for all kinds of things from building games to adding animations and effects to a website, a mobile app or even in a desktop application. It is widely used in web development, especially in HTML5 websites.
JS is a non-blocking language that does not wait for HTML and CSS to finish before it can do anything on the DOM (Document Object Model) elements. It can work with a variety of different engines, including browser and Node APIs, so it can be very useful for back end web development as well.
A call stack is a data structure that stores local variables, functions, and objects of those functions. It also has a reference to a memory address in the memory heap where these are stored.
It is a very good idea to use a call stack when developing your own code so that you know where everything is at any given time. It will make it easier to understand where you are in the execution context and what you’re doing.
The call stack also helps keep track of which functions are being called at any given time, allowing you to quickly identify where the function is that needs to be run. This will speed up your code writing and reduce the risk of errors.
Often the order of function calls is crucial, because it can have an impact on the DOM. Typically, the order of function calls will be based on the order in which they are loaded and parsed by the JS interpreter.
You can control how your scripts are loaded with the async or defer attributes on
