closePath() function in canvas is a way to draw a straight line from the current point back to the starting point, closing the current path. Here is an example of how to use closePath() in styling:

  1. Begin a path using beginPath() function.
  2. Use moveTo() function to set the initial point.
  3. Use lineTo() function to draw the desired shape.
  4. Use closePath() function to close the path.

var canvas = document.getElementById('myCanvas');
var ctx = canvas.getContext('2d');

ctx.beginPath();
ctx.moveTo(50, 50);
ctx.lineTo(100, 100);
ctx.lineTo(50, 100);
ctx.closePath();

// Style the path
ctx.strokeStyle = 'blue';
ctx.lineWidth = 2;
ctx.fillStyle = 'lightblue';
ctx.fill();
ctx.stroke();

ctx.closePath();  // Optional, as it is automatically closed after the fill() or stroke() functions


In this example, we create a path by moving to point (50,50), drawing a line to point (100,100) and another line to point (50,100). The closePath() function is used to close the path. We then style the path by setting the stroke style, line width, and fill color.
