Matheus Lima on what makes you senior: But if you strip away the title, the salary, and the years of experience, there’s one core skill that separates senior+ engineers from everyone else: reducing ambiguity. Everything else flows from that.
I liked this bit of JavaScript trivia from Cassidy Williams. There is a clear answer, and it’s something worth making sure you understand before heading into a job interview that involves JavaScript.
Adam Argyle is a talented developer who recently was on the job hunt and landed a new role. He’s got a lot to say about how that process went and certainly some good tips for any of y’all in that same position.
One of the dev jobs out there is DevRel or “Developer Relations”. A role like that is very likely going to involve teaching and helping people learn a products API. And, if the company has one, SDK’s around that API. Can you articulate the difference between them? At a minimum, that would be good to […]
I thought Ashley Willis did an excellent job explaining the role in What Is Developer Advocacy? (2025 Edition). We’re still here to serve developers. And we’re still doing the messy, meaningful work of bridging the gap between what a company thinks developers want and what developers actually need. I liked the perspective that it’s actually better for […]
Matt Smith on when to use map() vs. forEach() in JavaScript. Just one of those things I can imagine asking or being asked in a coding interview. Some interesting comments below the article as well.
What is the difference between ESLint and TypeScript? Perhaps that feels like a strange question as ESLint is a, uhm, linter, and TypeScript is a language that compiles to JavaScript. Josh Goldberg writes how there is some overlap: While ESLint and TypeScript operate differently and specialize in different areas of code defects, there is some […]
Steve Yegge makes the prediction in Revenge of the junior developer that this current wave of AI “agents” that help us code with more capability than just type ahead suggestions and refactorings, like file creation, command line usage, and more, is just the fourth wave of six. The fifth is an individual developer managing multiple […]
David Darnes asks: Is 2025 the Year of the ‘Design Engineer’? It’s arguably a bit of a new term and being used more and more as a job title. Like most job titles, it doesn’t have the strongest agreed upon definition, but it’s honing in around the front end and essentially a designer who can […]
Erick Merchant has some ideas for questions to ask a senior front-end-developer (as in, interview questions). They seem pretty decent to me, so if you’re shooting for a senior role, you should probably have answers for these things with a bit more detail than Erick lists.
Frontend Masters donates to open source projects through thanks.dev and Open Collective, as well as donates to non-profits like The Last Mile, Annie Canons, and Vets Who Code.
