Change Parameter explination under curvePoint() from:

Parameters

a Number: coordinate of first anchor point.
b Number: coordinate of first control point.
c Number: coordinate of second control point.
d Number: coordinate of second anchor point.
t Number: amount to interpolate between 0 and 1.

To Newer version:

Parameters

a Number: coordinate of first control point.
b Number: coordinate of first anchor point.
c Number: coordinate of second anchor point.
d Number: coordinate of second control point.
t Number: amount to interpolate between 0 and 1.

Reasoning

Under curve() they use:

curve(x1, y1, x2, y2, x3, y3, x4, y4)
-- x1 ------ y1------ x2 --- y2 ----- x3 ----- y3 ----- x4 ----- y4
control, control, anchor anchor, anchor, anchor, control, control

curvePoint() uses:
(If adding a curvePoint() under the X coords)

curvePoint(x1, x2, x3, x4)
control, anchor, anchor, control

But in the explanation, they say it uses:

curvePoint(x2, x3, x1, x4)
anchor, control, control, anchor

This confused me at first since I am new to programming in JavaScript and would like to help others to try not to confuse them

Start with the curvePoint() reference page linked in the issue and compare its parameter descriptions with the curve() documentation. Update the curvePoint() parameter explanations to match the stated control-point and anchor-point order, then verify that the published wording is consistent.
