What is front-end , back-end ? Can anyone give explanation to understand.
Front end is the visual part of a website (HTML,CSS,JS) and Back end is the part where all the server-requests such as logins, registrations, sending emails happen, mostly with languages / frameworks like PHP, MySQL, Node and so on (sometimes Python is used here too)
Roel React is used in front-end
Front-end is what they show you. Back-end is where they actually do the work. In applications the front-end would be a gui the user is working with. The back-end, well part of it, would be the error-handling routines to sort out what the user is doing.
Masthan Valli Please mark Roel's answer as best. He has provided more information and explanation than me.
