What Are Warps In Minecraft?

I Just Created A Server And I Have The Essentials Plugin Thingy. Its Mostly A Grief Free Multiplayer Server, BUT I Don't Really Know What Warps Do? And I Don't Know Any Good Ones? Can Any1 Help Me Please:/

It allows you to set teleports to a specific location.
For example, stand at an area (let's say a shop you built); and type "/setwarp shop". Then, if players type in /warp shop, they will teleport to the area you were standing when you set the warp.

Some common warps on servers are:
/warp spawn
/warp shop
/warp wild
etc…

Basically you can just name it anything you want

You set them up wherever you want and it lets you teleport there whenever you want.
