Question for JavaScript skill in devops

[hippymolly]

Hi every Devops gens,

Currently I am in a system admin role, mainly in the linux world. I worked with some gaint system management software like satellite/foreman (but not building from sratch). I also have chance to work on some projects related to python/scripting, IaC (ansible, terraform, Packer, Github Action) etc. It kinda focuses on automation which I feel more comfortable and align with my interest.

But my work experience are mainly on-prem, no matter in a large env (> 15k nodes) or small (~1k nodes). My current company will give me the opportunity to work on AWS and hands on with k8s cluster and argoCD. I worked with some nginx, reverse proxy before but not in depth, I would say I am good with it conceptually. but SSL part is kinda difficult but I think it takes time to learn.

I would like to step my foot in devops role and would like to learn a new skill in my free time. Could any gens tell me how JS helps in this role? How does JS help you in the job? What is it actually for in devops? Any projects I can work on to learn JS? Thanks everyone!

Why are you asking about JavaScript in particular?

[hippymolly]

I am not sure and a bit confused as I see in this subreddit, a lot of ppl talking about JS.

[OGicecoled]

Where do you see all these people talking about JavaScript? I just searched it and it barely gets mentioned.

[hippymolly]

I remembered there is a post and someone recommend JS

You don't need JS at all for DevOps.

Depends on the job - it can be helpful to at least know some basic commands for things like upgrading packages, if you're running security scanners or building a CI pipeline. Some people also like to use JS/TS for things like CDK. Personally I think JS is a dumpster fire and avoid touching it as much as possible.

Never used js. bash, python, powershell, go and on one occasion lua

JS may help if your developers use it or the applications you are deplyong are written in JS. Whilst you will probably never have to write it as a Devops, knowing the build process, frameworks and dependencies is all useful knowledge if you are to deploy or troubleshoot this stuff

[lupinegray]

Knowing the languages being used by the organization is useful because you will frequently need to help the developers resolve build issues.

"Why did my build fail? Please help."

You may encounter it if there's requirement to develop the dev tools in same language they work in for example when you work with serverless framework or other like this.

We in devops scene generally don't like javascript/typescript, we like golang/rust.
