1. 1. Syntax: EJS uses a syntax that is similar to HTML, allowing developers to embed JavaScript code within HTML templates using tags like <% %> and <%= %>. On the other hand, TypeScript is a superset of JavaScript and it adds static typing to JavaScript, allowing developers to write type-safe code and catch errors at compile time.

2. 2. Templating vs Language Extension: EJS is a templating language that is used to dynamically generate HTML content on the server side. It is primarily used to inject dynamic data into HTML templates at runtime. On the other hand, TypeScript is a language extension that adds features and capabilities to JavaScript, such as static typing, classes, interfaces, and modules, enabling developers to write more complex and scalable applications.

3. 3. Runtime vs Compile-time: EJS templates are processed at runtime by the server, meaning that the HTML content is generated dynamically on each request. This allows for flexibility and adaptability. In contrast, TypeScript code is transpiled to plain JavaScript during the build process and the resulting JavaScript files are then executed by the browser or server. This compilation step catches syntax errors and type mismatches at compile-time, reducing the chances of runtime errors.

4. 4. Browser vs Server Execution: EJS templates are executed on the server side, generating HTML content that is then sent to the browser for rendering. This can offload some processing from the client's device and reduce the amount of data transferred over the network. TypeScript, on the other hand, is executed on the client side, directly in the browser or through a JavaScript runtime environment like Node.js.

5. 5. Dynamic Content vs Static Types: EJS allows developers to easily inject dynamic data into HTML templates, enabling the creation of dynamic web pages. This makes it ideal for scenarios where the content needs to vary based on user inputs or other factors. TypeScript, on the other hand, focuses on enhancing JavaScript with static typing, ensuring that code is more reliable and easier to maintain by catching type-related errors early on.

6. 6. Ecosystem and Community: EJS has its own ecosystem and community, with resources, plugins, and libraries specific to EJS templating. TypeScript, on the other hand, benefits from the larger JavaScript ecosystem, with access to a wide range of libraries, frameworks, and tools that can be used alongside TypeScript.

In Summary, EJS is a templating language used for dynamic HTML generation on the server side, while TypeScript is a superset of JavaScript that adds static typing and language features to enhance JavaScript development. EJS focuses on runtime generation of HTML content, allowing for flexibility and dynamic changes, while TypeScript focuses on type safety and compile-time error checking, increasing code reliability. EJS has its own ecosystem, while TypeScript benefits from the larger JavaScript community.
