Calculate the Hamming difference between two DNA strands.
With LFE, you can use Lisp features while reaping the benefits of Erlang VM.
Take advantage of features such as Function Composition and Pattern Matching.
LFE runs on the Erlang VM, ideal for low-latency and fault-tolerant systems.
LFE brought homoiconicity to the Erlang VM, as it supports Symbolic expressions.
With LFE you can upgrade running systems without restarts, via hot code loading.
LFE supports metaprogramming via low-hygiene macros, ideal for creating DSLs.
Every language has its own way of doing things. LFE is no different. Our mentors will help you learn to think like a LFE developer and how to write idiomatic code in LFE. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in LFE - they'll help you discover the things you don't know that you don't know.
