Bootstrap is a free and open source front end web development framework.It is a giant collection of HTML,CSS and JavaScript code that is designed to help build user interface components.It is a free collection of tools for creating websites and web applications.It is used by many developers and according to the official Bootstrap site:It is the most popular HTML,CSS and Javascript framework to create responsive mobile first websites and web applications.It has several versions with the latest being the CSS 4. 


It was originally designed by a twitter employee, and was known as Twitter Blueprint. In 2011,it’s official version was launched with the name Bootstrap. 

Why use it?

There are many reason’s why bootstrap is leading the web frameworks race,some of them are: 

  • Reusability: Bootstrap contains ready made components,CSS styles and plugins that can be included directly into our code.Hence we can make use of these components and styles in our code,which will save time and helps in rapid development of the website/we app.
  • Mobile-first: The main priority when we make a website using bootstrap is to be mobile responsive.Mobile-first basically means that we build the website from a smartphone level and then scale it up to conform to the bigger sizes.
  • Easy to get started: It is easy to get started as it only requires the knowledge of HTML and CSS only.
  • Open source: It is open source in nature and completely free to download. 
  • Great Grid system: Bootstrap makes use of the powerful 12 column grid system which is easy to use and is very consistent.



AngularJs is a Javascript open-source front-end framework that is mainly used to develop single-page web applications(SPAs). It is a continuously growing and expanding framework which provides better ways for developing web applications. It changes the static HTML to dynamic HTML. It’s features like dynamic binding and dependency injection eliminates the need for code that we have to write otherwise.AngularJs is rapidly growing and because of this reason, we have different versions of AngularJs with the latest stable being 1.7.7. It is also important to note that Angular is different from AngularJs.


AngularJs was originally developed in 2008-2009 by Misko hevery and Adam abrons, and is now maintained by Google.

Why use it?

  • Easy to work with:All you need to know to work with AngularJs is basics of HTML, CSS, and Javascript, not necessary to be an expert in these technologies.
  • Time saving:AngularJs allows us to work with components and hence we can use them again which saves time and unnecessary code.
  • Ready to use template:AngularJs is mainly plain HTML, and it mainly makes use of the plain HTML template and passes it to the DOM and then the AngularJS compiler. It traverses the templates and then they are ready to use.

Key Difference between Bootstrap and AngularJS

Angularjs being a javascript framework gives us everything that is required for front-end development. It manipulates the DOM(Document object model) by extending HTML and its directives. It is mainly used to make web apps, as it provides all the necessary components and data binding techniques which makes it a suitable framework to use, whereas when we consider Bootstrap we know that it was developed by members of Twitter as a style guide initially, and is mainly used to make the websites more responsive with clean UI.
