Frameworks such as Django, Ember, Angular, React (library), and others provide best web development practices that allow you to maintain a project for the long term. Think about trying to first come up with the standard semantics on how to even structure your application. Then all of a sudden you need to develop a very complex DOM rendering engine and then somehow you need to test it! Oh snap. Frameworks come with important features to develop your app already baked in.
Frameworks eliminate the need to write a lot of repetitive code that you will find being used in many different applications. The advantage of efficiency will never be underestimated. You can expect to build a project in much less time than would be achieved writing code without a framework.
Advantages of Framework
1.Most of the popular frameworks are open-source (or available to use for free). They often also come with licensing that is not restrictive and allows to build a commercial product
2.In most cases, the framework has good documentation and support. It is worth mentioning that “good support” is a subjective issue at times. Typically, paid support will almost always be faster and more concise, but this also depends on the level of activity within the framework – as a framework like Ruby on Rails demonstrates with a massive community, which is renowned for its welcoming nature and good support too
3.Frameworks eliminate the need to write a lot of repetitive code that you will find being used in many different applications. The advantage of efficiency will never be underestimated. You can expect to build a project in much less time than would be achieved writing code without a framework
4.As far as a framework usually developed and tested by many different developers it can gain a strong level of security. It is extremely likely that many security risks are addressed and tested when the framework is being built
5.Integration: for building almost any type of application (including a website) where you want to store some data, you will typically use a database. There also exist many other tools that link to web development. Many frameworks will thus make it easier to link to these tools and also communicate with them
