使用方法
给定一个项目数组和期望的集群大小(n),返回一个数组的数组。每个子数组包含 n(集群大小)个项目,尽可能均匀分割。
import * as _ from "radashi";
const gods = [ "Ra", "Zeus", "Loki", "Vishnu", "Icarus", "Osiris", "Thor", "Apollo", "Artemis", "Athena",];
_.cluster(gods, 3);// => [// [ 'Ra', 'Zeus', 'Loki' ],// [ 'Vishnu', 'Icarus', 'Osiris' ],// ['Thor', 'Apollo', 'Artemis'],// ['Athena']// ]类型推断
cluster 函数为常见的集群大小(1-8)提供精确的类型推断:
// With explicit size parameterconst result1 = _.cluster(["a", "b", "c"], 1);// ^? [string][]
const result2 = _.cluster(["a", "b", "c", "d"], 2);// ^? [string, string][]
const result3 = _.cluster(["a", "b", "c", "d", "e", "f"], 3);// ^? [string, string, string][]
// Using default size parameter (2)const defaultSize = _.cluster(["a", "b", "c", "d"]);// ^? [string, string][]
// For sizes > 8, falls back to string[][]const largeSize = _.cluster(["a", "b", "c", "d"], 10);// ^? string[][]
const veryLargeSize = _.cluster(["a", "b", "c", "d"], 10000);// ^? string[][]
