  • Eclipse’s functionality is not as large as IntelliJ IDEA, but this development environment is distributed open-source.
  • You can leverage some of TypeScript’s advanced type checking and error reporting functionality in regular JavaScript files too.
  • In essence, software engineering combines the rigor of systematic design and development with the excitement of innovation.
  • It’s weird too because I learned more from the ide than the tutorials I was reading and that’s not how I typically learn.

Angular helps to make programming this type of functionality very easy. Not only can Angular help us make cool things like this, it offers a structured approach to writing our code that helps us keep it neat and readable. It also helps minimize bugs that could make their way into our applications caused by using JavaScript by itself. I’ll also provide some mini JavaScript tutorials to show you this versatile programming language in action.

Putting thought into your application architecture before you write a single line of code is an important starting point. I’ve seen many applications refactored when the developer didn’t consider how their application would scale. A component folder with only five files looks organized, but once there are 100 files, it’s hard to find what you are looking for. Any decision that will impact every single JavaScript file you potentially create should be carefully considered up-front. Now that you have a grasp on the language, it’s likely that the tutorials mentioned above resulted in a Node application to run your JavaScript. Browsers can run JavaScript without any help, but a web application that builds upon open source libraries and takes advantage of compiling and bundling assets is essential.
