❇️ IS PROGRAMMING JUST A MYTH ?

While math is often used in programming, it is not the only aspect of the field.

👉 Programming involves skills and concepts i.e -

╰┈➤ Design
╰┈➤ Communication
╰┈➤ Project management
╰┈➤ Logic Building
╰┈➤ Problem Solving Skills
╰┈➤ Various tools and technologies
╰┈➤ Etc.

So programming involves several other skills rather than just Maths.

What is the difference between a web developer and a full stack developer?

i. Web Designer
Technologies: Web graphics and animation (Adobe Photoshop, Illustrator, etc., Flash animation)

ii. Web Developer (Front-end)
Technologies: HTML, CSS, JavaScript, ActionScript (for Flash)

iii. Web Developer (Back-end)
Technologies:

One or more Server-side scripting language ~ PHP, JSP, CFM, NodeJS, Ruby (for Ruby on Rails framework ~ ROR), C# (.Net), Python, Perl, etc.
One or more databases (SQL) ~ MySql/MariaDB, PostgreSql, MS SQL, Oracle, etc.


Full stack developer:
‘Stack’ means a particular combo of technologies frequently used by a community of software or web application developers. My choice was the LAMP platform or stack: Linux OS, Apache Web server, MySql Database and PHP server side scripting. To be a full stack developer, not only you have to know front-end and back-end languages and SQL for database, you have to also have a very good working knowledge of server OS and web server administration. While a web developer might concentrate on one or two languages, a full stack developer will know the ins and outs of the web environment and all aspects of the web application. Frequently they are the ones who are responsible for building the architecture of an application from ground up.

A full stack developer will also additionally have knowledge of various other technologies and frameworks like JSON, XML, XSLT, JavaScript libraries (JQuery, Angular, BootStrap, PrototypeJS, ReactJS), NodeJs, Shell scripting, etc.
