let canvas = document.getElementById('canvas');
let context = canvas.getContext('2d');
context.beginPath();
context.strokeStyle = 'lightgray';
context.strokeRect(96,100,8,400);
for (let i = 100; i > 0 ; i = i-3) {
context.beginPath();
context.arc(100,100,i,0,360);
//rgba直接生成的棒棒糖颜色会很丑，你可以将这段代码注释看效果
// let color = `rgb(${Math.random()*255},${Math.random()*255},${Math.random()*255})`;
//通过hsl颜色表示法，生成"艳"一点的颜色
let color = `hsl(${Math.random()*360},80%,60%)`;
context.strokeStyle = color;
context.fillStyle = color;
context.stroke();
context.fill();
}
