I’ve been sticking to plain JavaScript because it’s faster for prototyping, but I feel like I’m getting filtered out of the application process. Is there anyone still hiring for JS-only roles, or has TypeScript officially become the "barrier to entry" for the entire industry this year?

I won't sugarcoat it: if you don't know TypeScript in 2026, your resume is likely going into the trash at any mid-to-large sized company. We moved our entire stack to TS two years ago and our production bugs dropped by 40%. It's not about being "slower" at prototyping; it's about the fact that AI coding tools work ten times better when they have types to lean on. It makes the code self-documenting. If you're a Full Stack dev, you need that type-safety to ensure your frontend interfaces match your backend API responses perfectly without constant manual checking.
Is the learning curve for "Advanced TypeScript" (like generics and mapped types) worth the time for someone just trying to get their first job?
TypeScript is the "lingua franca" of modern dev. Even the libraries you use are written in it. Learning it makes you a better programmer overall.
Spot on, Monica. Alicia, take a weekend to learn the basics. It’s the highest ROI (Return on Investment) you can get for your career right now.
Justin, you don't need to be a TS wizard day one. If you understand interfaces, types, and how to handle API responses, you're ahead of most. The "Advanced" stuff comes with time. Just stop using "any" for everything and you'll be fine in an interview.
