I’m coming from a Java background and I’m trying to wrap my head around the best practices for JavaScript and TypeScript in production environments. Don’t worry, I’m not here to start any language wars!
I’m wondering about the ideal coding style and structure for JS/TS projects. Should I lean towards functional programming or keep things more procedural? I’ve heard that going full-on OOP with TypeScript (like using abstract factories) isn’t really the way to go.
For organizing complex files, what’s the recommended approach? Should I just create a bunch of small, focused functions and export those instead of building classes?
Also, how do you folks typically handle data encapsulation in JS/TS?
If anyone has some good resources on JS/TS software design principles, I’d really appreciate it. Thanks a bunch for your help!
I’ve been working with JavaScript and TypeScript in production for several years now, and I can offer some insights. In my experience, a pragmatic approach works best - use functional programming concepts for data operations and light OOP for structuring larger components. Avoid heavy inheritance hierarchies.
For file organization, I’ve found that creating modular, feature-based structures tends to scale well. Instead of large classes, opt for smaller, focused functions grouped by domain. This improves maintainability and testability.
Regarding encapsulation, TypeScript’s access modifiers are helpful, but remember they’re compile-time only. For true privacy, consider using closures or the module pattern.
I’d recommend exploring the official TypeScript handbook and looking into design patterns specific to JavaScript, like the revealing module pattern. These resources helped me transition from more traditional OOP languages.
heya RunningTiger! coming from java myself, i totally get ur struggle. for js/ts, i’d say go for a mix of functional and oop. keep it simple, use classes when it makes sense. small focused functions r great for readability.
for data encapsulation, closures work well. check out the module pattern too.
As someone who’s been in the trenches with JS/TS for years, I can tell you that the landscape is quite different from Java. In my experience, a hybrid approach works best - use functional concepts for data transformations and OOP for more complex domain models.
For file organization, I’ve found that grouping related functionality into modules is more effective than strict class-based structures. This approach has improved our team’s productivity significantly.
Regarding encapsulation, TypeScript’s access modifiers (private, protected) are useful, but remember they’re compile-time only. For runtime privacy, closure-based patterns or WeakMaps can be effective.
One resource that really helped me was ‘Effective TypeScript’ by Dan Vanderkam. It offers practical insights into TypeScript’s nuances and best practices for larger codebases.
Remember, the key is to leverage TypeScript’s strengths without over-engineering. Keep it pragmatic and you’ll be fine.
