Misol

Keling, bir nechta chiziq chizaylik va birinchisiga butt qiymatini, ikkinchisiga - round, uchinchisiga - square qiymatini o'rnataylik. Qizil chiziqqa e'tibor bering - u belgilangan chiziq boshlanishini ko'rsatadi (round va square uning ustiga chiqadi):

html<canvas id="canvas" width="200" height="200" style="background: #f4f4f4;"></canvas>

javascriptlet canvas = document.querySelector('#canvas');
let ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'butt';
ctx.moveTo(75, 50);
ctx.lineTo(75, 150);
ctx.stroke();

ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'round';
ctx.moveTo(105, 50);
ctx.lineTo(105, 150);
ctx.stroke();

ctx.beginPath();
ctx.lineWidth = 10;
ctx.lineCap = 'square';
ctx.moveTo(135, 50);
ctx.lineTo(135, 150);
ctx.stroke();

ctx.beginPath();
ctx.lineWidth = 1;
