Modern Fortran (2008+) has built-in support for matrices, complex numbers, co-arrays (parallel programming), array slicing, etc. This makes it easy to write performant compiled code if you mostly deal with numerics.

Fortran has also added support for e.g. object-oriented programming, pure functions (no side effects for better optimization), and pointers. So idiomatic modern Fortran code looks very different from the “Fortran 77” code that many people might think of when they hear the name :).
