If you've worked with a language before that uses static typing and compile time type checking (Java, C#, and C++ immediately come to mind), TypeScript will be very easy to pick up. It'll just feel like a slightly different JavaScript-friendly syntax slapped onto the same set of core concepts. Coming from a background where I had written both C# and JavaScript before, TypeScript took all of one day reading docs and messing with the toolchain to start adapting it for the React app I was working on at the time If you haven't worked with a statically typed, compile-time type-checked language before, I think you owe it to yourself to learn one, whether or not TypeScript is the one you learn.
