functional-constructs-types

Functional programming constructs (map, filter, reduce) work better with TypeScript than imperative loops.

TypeScript's type inference works particularly well with functional constructs. They produce intermediate types that flow naturally, whereas loops require you to manually track types.

TypeScript infers the output type from the input type and the mapping function.

在循环中构建数组时使用。当类型不流经代码时使用。在考虑映射/过滤/归约时使用。 来源：marius-townhouse/effective-typescript-skills。
