ES6 vs Groovy: What are the differences?
- Syntax: One key difference between ES6 and Groovy is the syntax. ES6 follows JavaScript's syntax, which is more similar to C-style languages, while Groovy uses a syntax similar to Java.
- Type System: ES6 follows a dynamic type system, whereas Groovy follows a static type system. This means that in ES6, types are determined at runtime, while in Groovy, types are determined at compile time.
- Feature Set: ES6 offers newer features such as arrow functions, classes, and modules, which are not available in Groovy. Groovy, on the other hand, has features such as traits and builders that are not present in ES6.
- Community Support: ES6 has a larger community and more resources available compared to Groovy. This means that it is easier to find help, libraries, and frameworks for ES6 development.
- Execution Environment: ES6 code is executed in a browser or using Node.js, while Groovy code is executed on the Java Virtual Machine (JVM). This difference in execution environments can impact performance and compatibility with other systems.
- Compilation: ES6 code is typically transpiled to ES5 to ensure compatibility with older browsers, while Groovy code is compiled directly to JVM bytecode. This difference in compilation processes can affect deployment and maintenance of the codebase.
In Summary, the key differences between ES6 and Groovy lie in their syntax, type system, feature set, community support, execution environment, and compilation process.
This post is a bit of an obvious one, as we have a web application, we obviously need to have HTML and CSS in our stack. Though specifically though, we can talk a bit about backward compatibility and the specific approaches we want to enforce in our codebase.
HTML : Not much explanation here, you have to interact with HTML for a web app. We will stick to the latest standard: HTML 5.
CSS: Again if we want to style any of our components within he web, we have to use to style it. Though we will be taking advantage of JSS in our code base and try to minimize the # of CSS stylesheets and include all our styling within the components themselves. This leaves the codebase much cleaner and makes it easier to find styles!
Babel: We understand that not every browser is able to support the cool new features of the latest node/JS features (such as redue, filter, etc) seen in ES6. We will make sure to have the correct Babel configuration o make our application backward compatible.
Material UI (MUI): We need to make our user interface as intuitive and pretty as possible within his MVP, and the UI framework used by Google will provide us with exactly that. MUI provides pretty much all the UI components you would need and allows heavy customization as well. Its vast # of demos will allow us to add components quickly and not get too hung up on making UI components.
We will be using the latest version of create-react-app which bundles most of the above along many necessary frameworks (e.g. Jest for testing) to get started quickly.
For our front-end, React is chosen because it is easy to develop with due to its reusable components and state functions, in addition to a lot of community support. Because React is popular, it would be easy to hire for it here at our company MusiCore. Our team also has experience with React already. React can be written with ES6 and ES6 has a lot of popularity and versatility when it comes to creating classes and efficient functions. Node.js will be used as a runtime environment to compile the code. Node.js also has many different types of open-source packages that can help automate some of the tasks we want to do for the application. CSS 3 will be used to style components and is the standard for that.
Optimize-js
I will not describe this tool a lot here, because it's already good done by author on github
I just want to mention that this tool wrap up all immediately-invoked functions or likely-to-be-invoked functions in parentheses what is do a great optimization a JavaScript file for faster initial execution and parsing (based on my experience).
The performance of application where I've introduced optimize-js improved on 20% in a common (tested in Chrome and IE11).
- Clarification on Readme to the optimize-js
- Some of Nolan thoughts on the virtues of compile-time optimizations can be found in "Parens and Performance" – counterpost
Is it maintaining now? - Unfortunately, no (but feel free to send PR)
