Job Descriptions JavaScript Developers Should be Weary of in 2019

Recently, a thread over at r/javascript has me a bit fired up.

JavaScript today is not JavaScript of 2006, 2004, or prior. I repeat.

Modern JavaScript is not "just" JavaScript

Recruiters, and HR, please take note.

Lead devs,

I understand this language may have burned you, chewed you up, and made your life utterly miserable a decade ago.

This is not an acceptable excuse for attempting to hire a developer and stagnating their career progression with your outdated tech stack.

If Internet Explorer 11 and below are a required target, you better prepare to offer higher compensation for outdated technology.

Junior devs to-be,

Please take in consideration of where you see yourself in the future. If you've been building applications with technologies such as Ember, React, Angular, and Vue, please be cautious of job listings containing jQuery or "JavaScript" with no context.

If you are working heavily with ES2015 syntax and front-end frameworks, you are no longer just a 'front-end web developer'. You are an application developer. Don't let anyone try to cut corners with job descriptions.

However, job descriptions are just the beginning. You need to press the topic during the interviewing process if you have any doubt.

Legacy code is real, and you need to ask if you'll be spending 90% of your time in jQuery-land or what you thought you signed up for instead.

"I saw jQuery and React on the job posting, are you transitioning to React"?

"The interview question/tests are using some older syntax, is this indicative of your current codebase"?

Anyways, I scoured a job board to find a list of good and questionable job descriptions. Notice a common key-word in each of the good descriptions. If there is no mention of ES2015 (ES6) or higher, then you need to go on the offensive during the interviewing process.

Man, this hit close to home. I was job hunting recently, and I've seen a lot of job descriptions that made me nope out right away.
Thanks for the post. Many devs need to be aware of such recruiters/HR practices.

I think you are comparing two different job requirements. "Good Job Descriptions" requirement you put seems more for a JavaScript/Frontend developer and "Questionable Job Descriptions" more for a Full Stack developer. No?

For the good jobs, I used "ES6" as the lone keyword.

For the questionable jobs, I used "JavaScript" as the lone keyword.

That's where it can pick up descriptions that sound like full-stack, but some are actually just 'front-end'.

Maybe i'm looking in the wrong places, but I almost only ever seen job descriptions similar to your Questionable Descriptions section haha.

Hey, I'm not saying they're bad, but you're going to need to do a bit more digging once you get further along with them.

Also consider job boards for developers like here at, stack overflow, dice, and even on Twitter. Lastly, quite a few job openings and opportunities are brought up at local dev meetups.
