一个框架可以由不同的库组成。让我们举个例子。

Let's say you want to cook a fish curry. Then you need ingredients like oil, spices and other utilities. You also need fish which is your base to prepare your dish on (This is data of your application). all ingredients together called a framework. Now you gonna use them one by one or in combination to make your fish curry which is your final product. Compare that with a web framework which is made out of underscore.js, bootstrap.css, bootstrap.js, fontawesome, AngularJS etc. For an example, Twitter Bootstrap v.35.

Now, if you consider only one ingredient, like say oil. You can't use any oil you want because then it will ruin your fish (data). You can only use Olive Oil. Compare that with underscore.js. Now what brand of oil you want to use is up to you. Some dish was made with American Olive Oil (underscore.js) or Indian Olive Oil (lodash.js). This will only change the taste of your application. Since they serve almost the same purpose, their use depends on the developer's preference and they are easily replaceable.

框架:为应用程序提供独特属性和行为的库的集合。(所有材料) 库:一组定义良好的指令，为数据提供独特的属性和行为。(鱼身上的油) 插件:一个库(ui-router -> AngularJS)或多个库的组合(date-picker -> bootstrap.css + jQuery)的工具构建，如果没有它，你的插件现在可能会正常工作。

P.S. AngularJS是一个MVC框架，但却是一个JavaScript库。因为我相信Library扩展了本地技术(在这里是JavaScript)的默认行为。

这是我的想法(其他人也对此进行了合理化解释):

库是包含在代码中的东西。框架是应用程序的容器。

实际上，这取决于你给术语下什么定义。可能有很多不同的定义。

我认为下面的解释是基于我认为这个术语指的是什么:

确定的图书馆

确定性库保存的函数是基于A)函数输入或b)在函数调用之间以某种方式维护的状态确定的。

如果将逻辑依赖注入确定性库，则该逻辑必须符合具体的规范，以便库的输出不受影响。

示例:一个碰撞检测库，由于某种原因依赖于排序函数来帮助这些计算。这个排序函数可以配置为优化目的(例如通过依赖注入，编译时链接等)，但必须始终符合相同的输入/输出映射，以便库本身保持确定性。

非命定论的图书馆

一个非确定性库可以通过与它以某种方式访问的其他外部非确定性库通信来保存非确定性函数。

我通常将不确定性库称为服务。

示例:依赖于随机数字生成器服务来洗牌的扑克库。这可能是一个不好的例子，因为出于架构的目的，我们应该将这个库的不确定性方面推到外部。相反，通过采用预先洗牌的牌组，扑克库可以变得具有确定性和单元可测试性，现在这个库的用户有责任随机洗牌，如果他们愿意的话。

框架

框架介于确定性库和非确定性库之间。

任何依赖注入框架的逻辑在该函数实例的生命周期内都必须是确定的，但是不同逻辑的不同函数实例可以被注入到框架函数的单独执行中。

Example: Functions that operate on lists such as map, filter, sort, reduce, that expect to take in functions that are deterministic but can have varying logic for different executions. Note that this requirement only exists if these list operations advertise themselves as deterministic. In most languages, list operations wouldn't have this constraint. The core logic of such frameworks are deterministic, but are allowed to accept indeterministic logic at the risk of the user. This is generally a messy scenario to deal with, because output can vary widely due to implementation details of the framework.

实际上，根据使用的上下文，这些术语可以有很多不同的含义。

For example, on Mac OS X frameworks are just libraries, packed into a bundle. Within the bundle you will find an actual dynamic library (libWhatever.dylib). The difference between a bare library and the framework on Mac is that a framework can contain multiple different versions of the library. It can contain extra resources (images, localized strings, XML data files, UI objects, etc.) and unless the framework is released to public, it usually contains the necessary .h files you need to use the library.

Thus you have everything within a single package you need to use the library in your application (a C/C++/Objective-C library without .h files is pretty useless, unless you write them yourself according to some library documentation), instead of a bunch of files to move around (a Mac bundle is just a directory on the Unix level, but the UI treats it like a single file, pretty much like you have JAR files in Java and when you click it, you usually don't see what's inside, unless you explicitly select to show the content).

维基百科称框架为“流行词”。它将软件框架定义为

软件框架是可重用的 为软件系统(或 子系统)。软件框架可以 包括支持程序、代码 库、脚本语言或 其他软件帮助开发和 把不同的组件粘合在一起 软件项目的。各个部分 框架的部分可能是公开的 通过一个API..

所以我认为图书馆就是“一个图书馆”。它是对象/函数/方法的集合(取决于你的语言)，你的应用程序“链接”到它，因此可以使用对象/函数/方法。它基本上是一个包含可重用代码的文件，通常可以在多个应用程序之间共享(您不必一遍又一遍地编写相同的代码)。

框架可以是您在应用程序开发中使用的所有内容。它可以是一个库，许多库的集合，脚本的集合，或者创建应用程序所需的任何软件。框架是一个非常模糊的术语。

Here's an article about some guy regarding the topic "Library vs. Framework". I personally think this article is highly arguable. It's not wrong what he's saying there, however, he's just picking out one of the multiple definitions of framework and compares that to the classic definition of library. E.g. he says you need a framework for sub-classing. Really? I can have an object defined in a library, I can link against it, and sub-class it in my code. I don't see how I need a "framework" for that. In some way he rather explains how the term framework is used nowadays. It's just a hyped word, as I said before. Some companies release just a normal library (in any sense of a classical library) and call it a "framework" because it sounds more fancy.

从Web开发人员的角度来看:

库可以很容易地被另一个库替换。但框架不能。 如果你不喜欢jquery日期选择器库，你可以替换为其他日期选择器，如bootstrap日期选择器或pickadate。 如果你不喜欢在AngularJS上构建你的产品，你不能用任何其他框架来替代。你必须重写你的整个代码库。 大多数情况下，与框架相比，库需要更少的学习曲线。例如:underscore.js是一个库，Ember.js是一个框架。
