JavaScript scripts work by being included in an HTML document or executed as a separate file. When a web page is opened, the HTML document is parsed and the included scripts are executed.
The JavaScript engine reads and executes each line of code, following the order in which the code is presented. Depending on the code, the browser or another host environment may be interacting with the script. As the script runs, variables are initialized, functions are called, and events are triggered.
JavaScript is a dynamically-typed language, so variables can change type and value as the script runs. This allows developers to create highly interactive and dynamic web pages.
In summary, JavaScript scripts are designed to be executed on a web page and are responsible for creating dynamic behavior, such as animations, interactive forms, and responding to user input.
