water-design-utils v1.0.3

综述

集成 javascript 工具函数

使用

filterByType

import waterUtils from 'water-design-utils';
const arr = [1, '2', {}, []];

const filterArr = waterUtils.filterByType({
  array: arr,
  type: ['number', 'object'],
});
// filterArr = [1, {}]

generateByLength

import { generateByLength } from 'water-design-utils';
const arr = [1, 2, 3, 4, 5, 6, 7];
const generateArr = generateByLength({ array: arr });
// generateArr = [[1, 2], [3, 4], [5, 6], [7]]

memorize

import { memorize } from 'water-design-utils';
const sum = memorize(function (params) {
  let sum = 0;
  for (let i = 0; i < params.length; i++) {
    sum += params[i];
  }
  console.log('执行');
  return sum;
});
sum([1, 2, 3]);
sum([1, 2, 3]); // 再次调用因入参相同将不再执行计算，直接返回缓存结果
