Prioritize algorithmic efficiency and avoid unnecessary computational overhead, especially in type-level operations and validation logic. When multiple approaches achieve the same result, choose the one with better performance characteristics.

Key optimization strategies:
obj['_']['property']
over complex type inference patternsExample of optimization:
// Inefficient: Complex validation that always passes
const schema = type('Record<string, unknown.any>')
// Optimized: Direct type assertion since validation cannot fail
const schema = type.object.as<Record<string, any>>()
// Inefficient: Complex type inference
type Result = TValue extends Interface<infer TResult> ? TResult : never
// Optimized: Direct property access
type Result = TValue['_']['result']
This is particularly critical in type-level operations where “performance is our bottleneck in general” and unnecessary complexity can significantly impact compilation times and developer experience.
