The answer to this question is yes, but only partially. TypeScript is a multi-paradigm programming language and, as a result, it includes many influences from both object-oriented programming languages and FP languages.
However, if we focus on TypeScript as an FP language, we can observe that it is not a purely FP language because, for example, the TypeScript compiler doesn't enforce our code to be free of side effects.
Not being a purely FP language should not be interpreted as something negative. TypeScript provides us with an extensive set of features and allows us to take advantage of some of the best features of both the world of object-oriented programming languages and the world of FP languages.
