Var ctx=c.getcontext()

Question

c is for getting context or ctx ?

Answer 1

To make it more simple, in order to work with a canvas element that you have in HTML file, you have to do this in JavaScript:
var can = document.getElementById("...");
var c = can.getContext("2d");

***Note that variable names(can, c) can be chosen by you (you can change them as you wish).

Answer 2

ctx and c are just variable names they have nothing to do with canvas or context but here c would get the canvas element and ctx would access the canvas '2d' methods

Answer 3

thanks everyone.👍🙏

Answer 4

It can be assumed that 'c' is the variable for the page's Canvas element.
If not, then that code is erroneous.

var c = document.querySelector("#canvas");
var ctx = c.getContext("2d");

'ctx' is used to grab the Context of Canvas.

Answer 5

if you are talking about creating a context for a canvas, c is the html DOM element of the canvas. Then you use getContext("2d") to get a context from the canvas element. 3d canvas is supposedly in work.
