• API is a third party that provides access for developers to connect their applications on other web such as facebook and twitter.

2. Light
JS is client-side in that all processes that occur in a page will be processed by the client, the web browser. So the server only processes HTTP requests. If the fabric programming language is server-side. The flow will be a request from the browser to the server then the server receives the request and processes it. Then the results will be returned to the client via the browser. So the working step is request-process-response.

JS is able to collaborate with others like PHP. This makes a developer to be done quickly. If there is a function that PHP cannot do, it will be done by JS.

2. Not an OOP Programming Language
OOP developers are easy to develop because all the structures are clear and neat. It’s different with the old way of putting all its functions in one place. Developers will be confused by looking for functions that will be changed one by one from all existing functions.

3. Just as a Helper Only
Why is that? Because JS can not be used to create a stand-alone application or standalone app. It is different with other languages such as C++ or Java which can be compiled and then become an application with the language itself. If JS wants to create applications, it must be supported by other languages such as markup languages and HTML. Without HTML, JS cannot run perfectly. So the important key here if you want to play with JavaScript first is playing with HTML.

4. JS can be used to activate malicious code on the user’s computer.
5. Not always supported by various browsers and devices.
6. JS code snippets are quite a lot.
