Let's learn how to draw shapes with JavaScript and create fabulous Fibonacci flowers all from scratch with just plain vanilla JavaScript. In this HTML5 Canvas Tutorial for Beginners we will take a look under the hood to see how canvas 2D API draws shapes and then we use that knowledge to create colorful flowers and seashells using so called 'Fibonnacci flower formula', also known as 'Phyllotaxis' and 'Golden ratio'. This video will be very beginner friendly, you will be surprised how much you can do with so little JavaScript.

This HTML5 Canvas Tutorial for Beginners will be focused on the HTML canvas element and it's fundamentals. We will look into how it works under the hood and where are all these methods that allow us to draw shapes come from and we will learn how to draw shapes with JavaScript
Fibonacci sequence starts specifically with 0 and 1 and it is a very common interview question where you will asked to write an algorithm that returns numbers that create fibonacci sequence.
To draw so called fibonacci flowers we don't necessarily have to start with 0 and 1, we can also start with any two numbers we want, the only rule we cannot break is that each number in the sequence is the sum of the two preceding numbers

I literally yelled wow and flew back in my chair at 19:30 that is so cool and so simple. I haven't done geometry or trig since High School but this makes so much sense! Keep it up Frank.

Your tutorial is gold, because I didn't know front end would be so cool and friendly to implement

0:34 humm is it coffee? The first sniff is to see if it's too hot. It kinda is, but then Frank mans-up. The coffee left a little bit of after shock as you see his eyes jolt open for a sec. Coffee - it's Frank's secret to creative coding!

I really liked the effect you teach in this video. Thanks Frank

[basiccoder]

Thank you frank amazing tutorial i have shared this video with friends as well

[kencg]

Very fun tutorial. Thank you Frank!!! 👍✌

[LLLearning]

Thanks Frank this is great. I worked out if you add the following lines to the animate function and remove the return if statement, you can get a continuous refresh for a new flower design.
if(number > 250) {
ctx.clearRect(0, 0, canvas.width, canvas.height);
number = 0;
}
