Some Questions about JS canvas

Question

Could somebody tell me how canvas.beginpath() work?
I searched it and found that if I had use canvas.translate() than it didn't goto (0,0).

And if I use canvas.moveTo() without canvas.beginpath() it also can return to (0,0).

And use canvas.strokeStyle it may use the last color，I'm very comfused now...

Thanks for helping me :) Forgive my poor Eng Orz...

中文版： canvas.beginpath()是重置回哪裡?
canvas.moveTo()是不是不影響是否有canvas.beginpath()存在?
canvas.translate()的改變配canvas.beginpath()無法回去未改變前?
canvas.strokeStyle是以最後的顏色來判定對嗎?
或許這樣講比較直接><

Answer 1

What helped me was a YouTube video about the canvas. You can watch it here https://www.youtube.com/watch?v=eL1X8urHJmA

That's just an introduction, so watch their other videos too. Sometimes you need a lecturer to explain things better to you.

This is my greatest canvas work so far, https://code.sololearn.com/W0ZF06THFF8O/?ref=app

Answer 2

You start a path with canvas.beginPath() and the end it with canvas.stroke() or canvas.fill()

Answer 3

Uhhhhh Also sorry to unable to understand what you doubt
Can you show your code beside?

Answer 4

So after i watch the video is that canvas.beginpath() is used to reset the start point ,and tell compiler that i want to draw a path?,maybe it is not necessary?
