Chunk

介绍​

实现lodash的Chunk方法. Chunk<T, N>续保两个类型参数, T必须是一个元组, N必须是一个大于等于1的整数.

ts
type exp1 = Chunk<[1, 2, 3], 2> // expected to be [[1, 2], [3]]
type exp2 = Chunk<[1, 2, 3], 4> // expected to be [[1, 2, 3]]
type exp3 = Chunk<[1, 2, 3], 1> // expected to be [[1], [2], [3]]
ts
type exp1 = Chunk<[1, 2, 3], 2> // expected to be [[1, 2], [3]]
type exp2 = Chunk<[1, 2, 3], 4> // expected to be [[1, 2, 3]]
type exp3 = Chunk<[1, 2, 3], 1> // expected to be [[1], [2], [3]]
