On the client side, the browser controls JavaScript's runtime environment. Other than the implementation in dynamic features, another difference between the two JavaScript uses is in the resources the code can access. The meaning is slightly different in the two contexts but is related, and both approaches work together to enhance the user experience. Client-side JavaScript, on the other hand, dynamically generates new content inside the browser by using user-interface logic and modifying the webpage contents that are already on the client. Server-side code dynamically generates new content by using application logic and modifying data from the database. The difference between client-side and server-side JavaScript lies in the way they generate new content. Dynamic behavior is the ability to update the webpage display to generate new content as required. The word dynamic describes both client-side and server-side JavaScript.
The engine then interprets the bytecode and makes changes to the DOM.ĥ. Different events, such as a mouse click on a button, trigger the execution of the associated JavaScript code block. This code is an intermediary between the JavaScript syntax and the machine.Ĥ. The browser's JavaScript engine converts the JavaScript code into bytecode. During loading, the browser converts the page and all its elements, such as buttons, labels, and dropdown boxes, into a data structure called the Document Object Model (DOM).ģ. The browser loads a webpage when you visit it.Ģ. Here is an overview of how client-side JavaScript works:ġ. These functions make changes to the HTML and CSS. Web application developers write JavaScript code with different functions associated with various events, such as a mouse click or mouse hover. All major web browsers come with their own built-in JavaScript engines.
In this case, the JavaScript engine is inside the browser code. Client-side JavaScript refers to the way JavaScript works in your browser.
