What's the difference between a library and a framework?

In terms of coding, programming, application development and software development, "Library" and "Framework" are the two most used terms. Developers use the terms interchangeably, but most of remain empty-headed, wondering what these two terms actually means. For most of the new developers, these terms do not matter the most from its technical perspectives, though they are aware of the actual use of the two -library and framework.

I have asked many developers, especially JavaScript developers, they often seemed to be confident in terms of use but confused when it came to explaining these two technical terms. I have decided to short this issue out by providing these professional answers in both technical and non-technical ways so that everyone would understand them properly.

Let's find out what they mean;

What does Expert Say about Library and Framework?

"Library is something that you want to add something extra (it can be features or functionalities) on your website while Framework is something on which you want to build your model home." Well, that doesn't mean the library is used only as add-ons, it can also be used to build an entire project", said Saurabh Barot, Chief Technical Advisor at Aglowid IT Solutions.

What do the Library and Framework Really Means?

Library: 

Let's understand these terms in a more simplified manner. When we call a library that means you are looking something to add in your website. You call code which has been written some other developers. It means there's a set of that has already been written by someone else and you can call upon the code when developing your project. You can reuse the code so that you don't need to build it by yourself.

Framework: 

To understand the Framework, you need to understand the role of the library well. Library means you have a bunch of codes and you can call an appropriate library when needed. It will do its job and you don't require or need to know how these functions within the library work. That means you don't to learn it, though you need to know how to call them. Calling library code is an easy affair. When it comes to Framework, there are some similarities such as both library and Framework make your job easy and they are the code written by someone else.

However, in the case of the framework, you have some dissimilarity. For example, if you use Framework, you need to learn it first (if you don't know how to use the certain Framework). Here the case is just the opposite. In the case of the library, you call the code while the Framework calls your code. The Framework offers an application design, based on which the entire website will be built while the library offers functions which can be utilized within the website by calling upon the appropriate codes.

Let's understand these frameworks in Technical Term.

In technical terms, Framework and Library are based on the term "Inversion of Control." That means when you use a library, you are in control and you are 'in charge of the flow' and you, independently choose when and where to call them. When you use Framework, you are not in charge of the flow, rather the Framework calls you. Let's understand this through this image.

Conclusion

In short, the libraries and frameworks are the code written by someone else and help the developer to carry out common tasks. The framework works as a foundation or blueprint of the project and it tells you what you need while you need to call the library as the situation occurs and demand of the application.
