Is it worth learning TypeScript in 2026?
I've been working with vanilla JavaScript for two years already. Lately I see that everyone uses TypeScript in more serious projects. Is it worth investing time to learn it or is it just a fad?

If you already have two years of JavaScript under your belt, you can pick up TypeScript in a couple of weeks and then you'll immediately see why people use it - type checking saves you from stupid bugs that with vanilla JS you only discover in production.
It's not a trend, it's just that once you work on projects with more than one person or they grow even a little, maintaining the code becomes a mess without types. At this point, if you're already thinking about learning it, you might as well dive in instead of procrastinating - it's not like learning a brand new language from scratch.
Yes, it's worth learning TypeScript. If you already know JavaScript, the learning curve is much smoother than you think - basically you're learning a type checking layer on top of what you already know.
By 2026 it's become a de facto standard in serious enterprise projects, not just a fad, precisely because it reduces stupid bugs and makes refactoring way less terrifying when projects grow.
If you're thinking of doing frontend or backend professionally, it's a skill that opens quite a few doors for you.
It's not really a trend, even though I get why you might think so - it's more of a tool that's become standard in teams working on complex projects over the past few years. Two years with vanilla JavaScript already puts you in a pretty good position to learn it.
The time investment isn't that huge. Anyone who's comfortable with JS can pick up the basic syntax, and 70-80% of the actual work is learning how to structure types in a way that makes sense for your specific project. Rather than a massive investment, it's more about progressive practice. You can start on a small project, maybe refactor some code you've written, and learn as you go. You don't need to take a complete course before using it.
You really feel the difference when your code grows. With pure vanilla JavaScript, you start getting paranoid pretty quickly - "is this parameter actually a string? what does this function actually return?" With TypeScript you ask yourself those questions while you're writing, not when you're debugging at midnight. For serious projects and team work, it's basically become a standard for exactly that reason.
