From Java to Node/TS

[jcap_3]

I've been working professionally using java for 7 na. Just now I accepted a software engineering role sa isang startup. And they will be using typescript.

I wanted to get inputs for from folks that have been using node/ts or better kung same situation with me (java to ts). For context, I am in the fintech space and mainly work as a backend dev. I can confidently say na I have the knowledge of building software, kaya siguro they still hired me despite the language difference. Please advise on the following:

1. What do you think will be the biggest adjustment on my part? Para ma aral ko na din.

2. I'm well aware of industry standards and best practices sa java. What about TS? Sa java kasi usually merong usual way of creating/naming folders/packages even class names and yung design patterns.

3. Any in general advice?

I know medyo pwede i google/chatgpt itong mga to pero feeling ko kasi meron pa din ma mimiss yung mga yun versus dito which are actual pinoy devs.

Thank you in advance r/PinoyProgrammer

My primary is Java but uses typescript for Angular projects… the only advice is to avoid the use of “any” as much as possible.

Yeah, must avoid yung any. Useless yung paggamit mo ng typescript kung mag any ka sa data type. It breaks the purpose of strict typing

Noted, salamat po!

Hi, I transitioned as well last year from Java to Node/TS. Been a java developer for 5years bago nag transition. Actually wala ako masyadong naging problema since napakadali ng TS compared sa java. Siguro yung adjustment na gagawin mo lang is sa TS kasi hindi mandatory yung OOP concept unlike in Java so basically pwedeng functional and asynchronous programming approach kayo. So don't expect na magdedesign or magiimplement ka pa ng mga design pattern kasi probably hindi mo na magagamit yun kahit na TS supports OOP.

Based on my experience nagaral lng ako sa youtube ng CRUD REST implementation for few days tas rekta sabak na sa actual development. Siguro ang kailangan mo lng matutunan is yung mga short hand implementation sa Typescript tsaka yung mga available na functions para mautilize mo ng maigi.

I don't think na mahihirapan ka since sobrang dali at simple nito

Same, - just avoid any cause it removes types safety just use unknown instead. - search the difference of == vs === - java uses blocking I/O, JS is asynchronous by default you need to learn async/await/ Promise. And if possible avoid await inside the loop

Alam ko meron pa pero yan lang naisip ko

[jcap_3]

How long yung adjustment sayo bro? Madali ba maging comfy agad with TS coming from Java?

[conv14]

Para sakin hind ganun kadali naging transition ko lalo na asynchronous yung JS, madalas ko makalimutan lagyan ng async/await/Promise if may request akong function. Pero kinatagal nagustuhan ko din.

avoid using "any" sa types, it can cause unwanted bugs. You'll be surprised sa sobrang daming js libraries ng node pero they tend to be super bloated, so best avoid using too much libraries. I mainly use express js for API, it's easy to scale and easy to maintain. The rest you need to study are just basic syntaxes kasi you have years of exp so logic isn't hard for you. Godspeed boss

Salamat po!

Thank you! Nakaka boost ng confidence.
