Good at building upon concepts learned in JS; much better for coding projects and providing a scaffold to ensure your code compiles and runs with as few errors as possible by catching them well in advance. Definitely recommended to upgrade your JS skills to TS!

Got questions? We've got answers

Yes. TypeScript builds on JavaScript, so you should understand JavaScript fundamentals first. Boot.dev's Learn JavaScript course is the prerequisite for this course.
