F to the A oracle to the Q
Is TypeScript easy to learn?

As always, an answer to these questions is 'it depends'. It is easier if you know some JavaScript or ever worked with typed languages. If not, then Typescript will be a bit harder than JavaScript.

Should I learn JavaScript or TypeScript?

There is no need to learn TypeScript explicitly. It is good to learn, because it forces you to write better JavaScript code, complies to JavaScript but, essentially not required for other frameworks. ES6 is enough JavaScript to work on all libraries and frameworks.

Is TypeScript easier than JavaScript?

People who work with both say that TypeScript is slightly more difficult to learn, but easier to work within the long term.
