Lodash教程

Lodash collection

Lodash 有许多易于使用的方法来帮助处理集合。本章将详细讨论它们。

Lodash 提供了各种方法来处理下面列出的集合-

Sr.No.	Method & Syntax
1	countBy _.countBy(collection, [iteratee=_.identity])
2	every _.every(collection, [predicate=_.identity])
3	filter _.filter(collection, [predicate=_.identity])
4	find _.find(collection, [predicate=_.identity], [fromIndex=0])
5	findLast _.findLast(collection, [predicate=_.identity], [fromIndex=collection.length-1])
6	flatMap _.flatMap(collection, [iteratee=_.identity])
7	flatMapDeep _.flatMapDeep(collection, [iteratee=_.identity])
8	flatMapDepth _.flatMapDepth(collection, [iteratee=_.identity], [depth=1])
9	forEach _.forEach(collection, [iteratee=_.identity])
10	forEachRight _.forEachRight(collection, [iteratee=_.identity])
11	groupBy _.groupBy(collection, [iteratee=_.identity])
12	includes _.includes(collection, value, [fromIndex=0])
13	invokeMap _.invokeMap(collection, path, [args])
14	keyBy _.keyBy(collection, [iteratee=_.identity])
15	map _.map(collection, [iteratee=_.identity])
16	orderBy _.orderBy(collection, [iteratees=[_.identity]], [orders])
17	partition _.partition(collection, [predicate=_.identity])
18	reduce _.reduce(collection, [iteratee=_.identity], [accumulator])
19	reduceRight _.reduceRight(collection, [iteratee=_.identity], [accumulator])
20	reject _.reject(collection, [predicate=_.identity])
21	sample _.sample(collection)
22	sampleSize _.sampleSize(collection, [n=1])
23	shuffle _.shuffle(collection)
24	size _.size(collection)
25	some _.some(collection, [predicate=_.identity])
26	sortBy _.sortBy(collection, [iteratees=[_.identity]])

找工作要求35岁以下，35岁以上的程序员都干什么去了？

长久以来，一直有一个问题困扰着技术人——如何打破“程序员的35岁职业魔咒”，这一天迟早会到来，或早或晚。
