Anton Pets How FP Made Grammarly Codebase Error-free & Predictable

Crafting UI systems with a complex mutable state spread across the network is inherently difficult. This problem is still very new and thus doesn’t have clear answers. At Grammarly, we have found the methodology that lets us tackle this complexity while keeping our codebase error-free and predictable. Our approach combines the pragmatic usage of functional programming with static typing. I will show you how functional programming can solve typical front-end problems in an effective and elegant way.
