In this case, the blog can simply embed a third-party's web application, meant to read code and produce its output in situ. It would be too early to explain all that technical jaron at this stage.Īs a simple example of an, one that you would've probably already witnessed before, suppose a blog has to embed a code snippet along with a program that can run that code (sometimes on another server) and show the response/output live, something like Codepen or JSFiddle. The fact that certain things are easier with s will become much clearer to you once you become a complete developer, knowing how to develop custom video player, ad libraries, and interactive utility apps, using JavaScript and other web technologies. ![]()
