If you have a background in Web Development then you can understand that frameworks are so much important to build a website.

So in this article, we can determine why Frameworks are so much important for Web Developers?. Are you interested to learn the JavaScript Frameworks and want to get all the information regarding the frameworks?. So this article is completely for you in which I have included all the kinds of stuff linked to the frameworks. Such as Definitions, What are J.S.

What is the JavaScript language?

JavaScript is a client-side language and scripting language, a cross-platform that is essentially designed for creating dynamic websites or web pages alive. It is a highly successful language which is created by Brandan Eich, a Netscape employee in September 1995. it becomes one of the most powerful languages for all web developers for the development of web pages or programmers who are working on the Internet in a just few years(approx. 20 years).

Why you have to learn J.S. for Web Development?

JavaScript is one of the popular languages by which developers are executing so wonderful website and mobile applications.

With the help of 3 languages(HTML, CSS, and JavaScript) you can easily build your own website. Now how these 3 languages work on your web pages. Following are the features of these 3 languages:

  1. HTML– It stands for HyperText Markup Language. It is used to design the structure of the web pages. With the help of Headings, images, navigation bars, etc we can easily establish a beautiful website. You can easily check the HTML of all the websites by just right click of the mouse and go to page source you will get all the HTML tags( it will look complicated).
  2. CSS– CSS stands for Cascading Style Sheets. It is used to give a beautiful design to your web page. With the help of font-size, color, font-family, background images, etc. you can build a beautiful website so it’s up to you how amazing a website you can make.
  3. JavaScript– As you know J.S. is used for the development of web pages.

Undoubtedly JavaScript is extremely recommended for web development. Now when we are operating on any website, Web developers constantly try to write precise and effective code which makes their work smooth and can be completed in a very limited period of time. So for that Web developers are using Frameworks that enhance their work. Let’s see what is frameworks.

What are JavaScript Frameworks?

JavaScript frameworks are application frameworks that are written in JavaScript language. It is pre-written code that all the programmers especially developers use for their bizarre persistence such as designing the websites to make websites further responsive, make the website more attractive, add some more features, etc. Because of this most website developers prefer to use frameworks. Frameworks make their work more relaxed and more constant.

Why you have to use Frameworks?

To make your work easier. Web Developers always try to write less code and make websites more effective. So for that Frameworks helps you by providing pre-written codes and ready-to-use functions. Developers can use these functions for creating their own functions and use them whenever they needed, and many more things which quite save time. So Frameworks play a hugely vital role in designing Web pages.

Now a very important question arrives that how many frameworks are there and which frameworks are best to implement?

Basically, there are so many frameworks(approx. 20) that are using to build websites. You can use anyone. But for amazing performance and features, we have some popular frameworks which we will discuss in this article and in the upcoming articles also( each framework in the full detailed way).

Following is the listing of the topmost 7 frameworks:

3. Vue JS:

Vue is an open-source J.S. framework that is designed for building UIs and single-page applications. It was created by Evan You and released in 2014. Currently, more than 64k websites and some giants companies such as Stack overflow, PlayStation, etc. are using Vue js.

Following are the features of Vue js:

  1. Virtual DOM

  3. Event Handling
  4. Animation/Transition
  5. Templates

4. jQuery:

jQuery is a fast, concise, and feature-rich JavaScript library that was created by John Resig in 2006. It helps developers not to write various lines of code. You just simply use methods that you can call in a single line of code.

According to google jQuery is used by almost 95.9% of all websites. And almost 106750 giant companies such as Uber, Twitter, Udemy, etc. are using jQuery.

Following are the features of jQuery:

  1. Lightweight
  2. Html manipulation

After that, it was changed to Ember.js.

Almost 34k websites are using Ember.js. There are some companies also such as LinkedIn, Accenture, Digital Ocean, Oyo, etc.

Now lets us see by a graph that which framework is more popular, emerging and futuristic.

So we can easily say that React and Angular are the most popular frameworks which developers are using.

How J.S. frameworks are different from libraries?

Basically, we have seen so many informative points such as What are J.S. frameworks, What are the popular frameworks developers are using. So now we have clear concepts that every developer thinks that J.S. frameworks and libraries are the same. But it’s not.

Firstly let us define What is libraries and frameworks?. Libraries are the set of JavaScript codes that are used for the development of J.S. applications. And Frameworks are the collection of JavaScript libraries that having some set of rules to perform tasks. Secondly, The main difference between Libraries and Frameworks is the set of rules, libraries have fewer rules compared to frameworks. Secondly, whenever you have the power to call the code then it will be libraries on the other hand if Frameworks has the power to calls your code for further development then it is a framework. So both are a really different and very significant concept which is frequently asked in interviews so always keep in your mind.
