Full Stack Developer

A person who can develop both sides of software, i.e. client-side and server-side is called as a full-stack developer. They must be acquainted with HTML and CSS. A full-stack developer should also how to program a browser using JavaScript, Angular or JQuery, etc. They must even know how to program a server using PHP, Node, Python or ASP and even know to program database using SQL, MongoDB or SQLite. They can easily switch between front-end and back-end development if required because they have enough knowledge about other programming languages also.

Some of the popular stacks are as follows:

a) MEAN stack: MongoDB, ExpressJS, AngularJS and Node.js

Now we have understood the difference between front-end, back-end and full-stack developer. Every developer has a role to play. Though, a full-stack developer knows how to perform both the tasks but they do not need to do both the work. They work for a particular developing process but has enough knowledge and can switch to any end whether it’s front-end or back-end whenever require.
