I've used typescript with lodash/fp (a similar FP library) and I found it to be an absolute joy. Once the team decided to really use lodash/fp for data manipulation, and the basis for composable logic, we really start to move quick. We came up with our own linting guide, and guidelines for writing extensible and composable code. I've never coded in Scala, but I've shipped production code in languages that support multiple paradigms. Conventions are important. Things need need to be agreed upon and done in a certain way or your code base will become a tangled mess.
