What is a framework?

A programmer needs to quickly solve a typical problem. To avoid writing code, he uses a special billet to reduce the amount of work. This billet is called a framework. About why they are needed and what they consist of, read below.

What is a framework and what does it consist of?

A framework is a structural program that defines some of the components of a program. It has:

• Written code that represents the framework.
• A certain set of rules that do not allow breaking the potential program.
  
• Tools that give an opportunity to simplify the development.
  

A framework is considered an intermediate option between the full writing of code and the use of CMS.

Frameworks also have an architecture. Conditionally it can be divided into 3 components:

• Model. Here we have everything about data and how to interact with it.
• Display. The data from the Model is displayed in a way that is user friendly.
  
• Controller. Responsible for the interaction between the user and the system. Simply put, it is the one that redirects data from the system to the user and vice versa.
  

What are frameworks for?

Now sites are made with the help of constructors, and the program written from scratch can better meet the needs of the customer. Therefore, first let's analyze the pluses of the framework, and then we will tell you why they are better than the above options:

• Frameworks speed up the work. A ready-made template is simply filled with content and improved.
• It makes the work easier. That's why it's useful for beginner programmers to go to the search engine less often. And also if you have already worked with one project from a framework, it will be easier to work with the rest in the future.
  
• Frameworks reduce the number of mistakes made.
  
• They are safe. Successful frameworks are tested for vulnerabilities. This doesn't give absolute protection, but it's still useful.
  

Frameworks can be more beneficial than writing code from scratch, because less effort is spent, but the benefits are almost the same. Also building websites can be better than constructors for the following reasons:

• Code in builders can have optimization problems. All because it is too big. What this means for you is that some sites will load slower.
• You can't edit the code manually in most builders. This can create problems for the business.
  
• SEO optimization can be slow.
  

What kind of frameworks are there?

They are also divided into subspecies. All frameworks are related to programming languages. Choosing them, you should learn one of the languages.

Frontend framework

Help you work on the front-end of the site, such as the interface.

React

It is also referred to as React JS. It can be called either a library or a framework. But it is in demand, which is the most important thing. It has the following features:

• Extensive community. Read tutorials, watch videos, communicate with other programmers.
• Can interact with other technologies. For example, there is React Native, which allows you to work with mobile devices.
  
• Has a virtual DOM. What this means for you is that the browser will be more malleable when receiving updates.
  

Angular

A specific framework from Google. Among the features:

• Makes it easy to create seamless pages.
• Free, has open source code. This means that the framework can be augmented.
  
• Consists of components. The site is assembled like a constructor.
  
• Support from Google and quality documentation.
  

Jue.js.

Initially popular for being simpler than React. It is based on HTML, CSS and JS standards. Here is what this framework has to offer:

• Single-file components. These combine HTML, CSS, and JS components into a single file.
• Jue.js is easier to embed in services written in other frameworks. This makes it more reactive.
  
• The low threshold of entry allows you to learn this framework faster.
  

Framework for the backend

Need sides of the service that the user doesn't see.

Django

A framework for Python, which is at the top in popularity in 2024. Has the following differences:

• There is the DRY (don't repeat yourself) concept, which allows you to reuse the same code elements repeatedly rather than writing new ones.
• Great functionality allows you to create an application without using third-party tools.
  
• Compared to programs written from scratch, Django often wins. All because it is supported by both the developer studio and third-party programmers.
  

Laravel

PHP framework with a clear syntax. Useful for the following:

• Code is easier to read.
• Suitable for newbie backers due to its brevity.
  
• There is a template system that simplifies the creation of dynamic web pages.
  

How does a framework differ from a library?

With a library, you get a set of tools that allow you to write programs and complete freedom of action. A framework assumes the presence of rules and structure. In fact, it is also a library, but only it sets the development of your project.

Tips for choosing a framework

There are dozens of frameworks, only in JS it can be Angular, React, Next.js, Node.JS, etc. So let's give some advice on the topic of choosing options:

1. What do you know and how much free time do you have? If you know almost nothing - get busy mastering your chosen language, and leave frameworks for later.
2. How many people support the framework? Choose a popular or emerging one if you want to increase the chance of getting a job.
   
3. What will you lose if you don't learn the given framework? A question with this wording can be attributed to anything related to learning.
   
4. Have you looked at job openings for a future position? If not - get on it, so that the time spent is not wasted.
   
5. What do you plan to do? If writing websites - frameworks become a necessity. Because a self-written site is often unreasonably expensive. The same Yandex.Market is written on Userver. But when developing programs, they can wait.
   
6. What additional criteria should it have? How should caching work in the framework? How good should debugging be? What about backwards compatibility, etc.
   

Well and pay attention to what you personally need.
