I'm working on Sharepoint as Front-end Developer for now 4 years but now I feel I didn't have basic knowledge about this technology. Below are some questions in my mind and your input is really appreciated:
What is Sharepoint?
Why we use Sharepoint?
In which language we can code in Sharepoint?
What is the role of Front-End Developer in Sharepoint?
There is no single answer to your question. The simple answer is in its name "Share" + "Point".
A place where people can Share information. Where people are looking for and generating information.
There are variuos threads asked about the same question, maybe it will help you:
For Front end development you can use variuos languages for coding like:
C#
Javascript(jQuery, Angular, react, etc.) : REST services, SPServices, JSOM, etc.
HTML5 and CSS3 for custom solutions and dashboards.
Since you have already worked for 4 years as a front end developer for SharePoint , let me answer to you in a way it feels relevant.
1.Which technologies can be used to code in SharePoint ?
So as a front end developer you can use technologies like HTML, CSS, and JS, as well as common web toolkits/frameworks and technologies (text editors/IDEs, jQuery, AJAX, web servers; you get the drift).
2.What exactly SharePoint is and why is it used?
Sharepoint is a web application platform developed by Microsoft. Though you’ll find a wide array of explanations as to what Sharepoint is. It’s most often used as an intranet site for businesses of all shapes and sizes, offering a range of features:
