The main benefit of purely functional systems is function composition. The ability to build entire programs through the composition of function primitives. Composition without dependencies. The problem with javascript is that this concept is entirely lost on react developers. Due to the untyped nature of javascript and it's close linkage with html. HTML is made up of dependent components and this essentially puts dependency injection into javascript leading to JAVA like issues that the functional paradigm was suppose to solve.
