lodash使用方法大全

let arrLodash = [1, 2, 3, 4]
console.log(Lodash.chunk(arrLodash,2))  //将数组切割，变为二位数组  [Array(2), Array(2)]

let arrCompact = [1, 3, 0, NaN, undefined, '', 9]
console.log(Lodash.compact(arrCompact))  //去除假值  [1, 3, 9]

let arrUniq = [1, 1, 3, 6, 6, 9, 4, 9]
console.log(Lodash.uniq(arrUniq))  //数组去重  [1, 3, 6, 9, 4]

let arrReject = [{ id: 1, name: '李狗蛋' },{ id: 2, name: '叶良辰' },{ id: 3, name: '赵日天' },]
console.log(Lodash.reject(arrReject,['id', 2]))  //根据条件去除数组元素  [{ id: 1, name: '李狗蛋' },{ id: 3, name: '赵日天' },]

let arrPick = { id: 111, name: '龙傲天', age: 18 }  
console.log(Lodash.pick(arrPick,['id', 'name']))  //对象中筛选属性  {id: 111, name: '龙傲天'}

let arrKeys = { id: 0, name: '陈车仔', age: 'One year' } 
console.log(Lodash.keys(arrKeys))  //得到对象中所有的属性名，以数组的方式保存   ['id', 'name', 'age']

let arrCloneDeep = { id: 0, name: '陈车仔', age: 'One year' } 
let cloneDeepObj = Lodash.cloneDeep(arrCloneDeep)
cloneDeepObj.name = '陈乌冬'
console.log(cloneDeepObj)  //深拷贝   {id: 0, name: '陈乌冬', age: 'One year'}
console.log(arrCloneDeep)  //深拷贝   {id: 0, name: '陈车仔', age: 'One year'}
