Where is JavaScript executed?
No. JavaScript is downloaded into the client's browser and executed there. With one caveat. Apache has a server-side JavaScript module that reached public experimental phase. It proved the concept, but saw little (if any) actual real world use.
What is client program?
As far as web programming is concerned, client side programming is code that runs in the web browser, rather than the web server. JavaScript is an example of client side scripting because the code is sent to the browser, at which point it is executed. PHP is an example of server side scripting because the code is executed on the server, and the resulting code is sent to the browser and displayed.
How do you connect javascript using php?
Any communication between Javascript code and PHP code needs to be instigated by the Javascript. This is because Javascript is a client side script and PHP is server side. The server can't force data to the browser; it can only reply to requests. The technique of using Javascript on the client side to talk to server side scripts is referred to as AJAX (Asynchronous Javascript And XML). There are several libraries available for simplifying it's usage, and many online tutorials.
Why javascript is not server side programming?
JavaScript is primarily known as a client-side programming language, which means it runs in the web browser on the client's device (e.g., computer, smartphone). However, it can also be used on the server side, but it's not traditionally considered a server-side programming language like Python, Ruby, Java, or PHP. Here's why: Execution Environment: JavaScript is designed to be executed in a web browser. Its primary role is to enhance the interactivity and functionality of web pages by manipulating the Document Object Model (DOM) and making asynchronous requests to servers. Language Design: JavaScript was originally created for client-side scripting, so its core features and libraries are tailored for browser-based tasks. Node.js: While JavaScript is primarily a client-side language, Node.js, a server-side runtime environment, was developed to execute JavaScript on the server. Node.js extends JavaScript's capabilities to server-side scripting, but it's distinct from traditional server-side languages in terms of its runtime environment and architecture. Concurrency Model: JavaScript's single-threaded nature, designed for the browser, can limit its effectiveness for certain server-side tasks that require handling multiple concurrent requests efficiently. Node.js addresses this limitation by using an event-driven, non-blocking I/O model. Server-Side Languages: Server-side programming languages like Python, Ruby, and PHP are specifically designed for building server-side applications and offer extensive libraries and frameworks for tasks such as database interaction, file handling, and server management. In summary, JavaScript is primarily a client-side programming language, but it can also be used on the server side, thanks to environments like Node.js. While JavaScript's role has expanded to include server-side scripting, And if you are looking JavaScript Online Course then my suggestion is to contact Croma Campus.

What are the differences between client-side scripting and server-side scripting?
Web 2.0 applications have a server side and the choice of technologies to use server side is even more open than that client side. Client side is the user;s end of the experience, while server side is based on the server's end. As a developer, you can't impose a specific environment or browser client side because you must count on what is installed by your users and that's a severe restriction. Server side, however, you decide which platforms, operating systems, programming languages, frameworks, and libraries will be used. The choice that has the most impact on the architecture of your applications is usually the programming language. Server side, any programming language can be used to implement various Web applications and the most popular choices are scripting languages such as PHP, Perl, Python, and Ruby, and interpreted languages such as Java and C#. Client side scripts are executed and changed by the user on his side (the client side), while server side scripts are executed and changed by the user on the server. Server side scripts provide much more functionality for and by the wide variety of users (and their respective computer/browser settings) all around. Client side Scripting is possible to be blocked , where as server side scripting can't be blocked by the user , so if you validate using CLIENT SIDE only , and client side scripting blocked then even validation can not be done and directly even wrong data can be accepted and thus makes a flaw in the system.

How does form validation differ in JavaScript and PHP?
