It is also considered an event (session)-based programming language, as everything you do on a website triggers an event.
Top 10 Uses of Java Script Programming Languages
1. Dynamic Content
2. User Interaction
You can implement interactive elements like buttons, forms, and sliders. An e-commerce platform allowing users to interactively customize product options, such as color and size, using dynamic buttons and dropdown forms are examples of Java Script uses in web development.
3. Asynchronous Requests
A WordPress blog website asynchronously loads additional blog posts when a user scrolls down, providing a continuous browsing experience without the need for a full page reload. This avoids disruption and offers a more fluid interaction for users exploring the content.
You can create smooth and engaging visual effects. For example, on a beautician’s website, you can create smooth and visually appealing animations when showcasing different beauty services or before-and-after transformations or sliders.
5. Form Validation
You can validate user input before submitting forms. For example, a blog with a comment section that validates user inputs (e.g., email format, required fields) before submitting, providing real-time feedback to users.
6. DOM Manipulation
You can Modify the Document Object Model to change the structure and style of a page. You can create a dynamic popup utilizing DOM manipulation to showcase live notifications or updates triggered by user actions on the web page.
7. Event Handling
You can respond to user actions, such as clicks and keypresses such as subscription form submission or newsletter link after the post.
8. Cookies and Local Storage
You can store and retrieve data on the client side. For example, an e-commerce website’s header that stores user preferences (e.g., currency, language) locally using cookies, is created to provide personalized user experience.
You can enable uninterruptible data exchange between the client and server. In an ecommerce site by implementing AJAX you can dynamically update the shopping cart without refreshing the entire page.
10 . Client-Side Routing
Client-side routing is a technique used in web development where the navigation between different pages or sections of a website is handled on the client side (in the browser) without requiring a full page reload from the server. This approach is commonly associated with single-page applications (SPAs).
